ALL ABOUT SPACE
Just like in movies let us explore the facts about space. Also, we enjoy the movies directed in the space or universe.
Space is infinitely large, infinitely fascinating and most of all infinitely scary.
However, everyone loves the mind blowing effects and the amazing fights in the space.
Every week there are new space discoveries. As a result, we have came up with a lot of facts about space which you will love to read.
Hope you will get a lot of information as well as a great knowledge about our solar system. However, we did a comprehensive research in the deep of the universe. We did this to bring up all the best facts about space for you.
Here are the top 111 most interesting facts about space that you are going to love.
Our whole solar system has a total of 176 moons as confirmed till now. However, some of the moons are even greater in size than the planet Mercury itself.
But still Mercury and Venus in our solar systm posses no moons revolving around them.
A team of astronauts from our world were observing a star. It was revolving around a Black Hole. Black Hole, situated at the centre of our galaxy.
However, the star has got a lot closer to the black. That it will lose its light and energy if it catches black hole.
Most of the people think that the hottest planet is Mercury. This is because it is the closest planet to the sun.
However, the story changes when you get to know that Venus is the hottest Planet in our Solar System.
Venus has a lot of gases in his atmosphere, this creates a Greenhouse Effect. Also this causes the temperature to rise at 462 Degree Celsius (862 Degree Fahrenheit)
Therefore, this is the main reason why Venus is the most hottest planet in our solar system.
Our Solar System is a around about 4.75 billion years old as by now.
Scientists estimate that round about 5 years later the sun will expand at a much greater size. Therefore, the sun will swallow the Earth within itself.
Enceladus is one of the smaller moons of the planet Saturn. Also, this moon reflects around 90% of the light by sun
However, this moon has icy surface. This is the reason that it reflects the light rather than absorbing it.
You guys would be thinking of the Mount Everest. But let me make it clear, it is the highest mountain in world.
Olympus Mons is the highest mountain located on Mars. This mountain is 3 times higher than Mount Everest.
This Mountain is 25 km high. Also it is as wide as Arizona (about 374,015 ft²)
However, the light travels in the universe at a speed of 186.411 miles (300,000 km) per second.
Also, if we calculate this we get to know that light travels a distance of 5,903,026,326,255 miles in a year.
Make sure to read the fact no. 7 above.
However, a modern spacecraft would take around 450,000,000 years approximately to reach the centre of Milky Way.
The diameter of the Sun is about 109 times the diameter of the Earth.
However, the sun is so large that whole earth can fit inside the sun 1,300,000 times approximately.
Also, the sun contains almost 99.85% of the total mass of our solar system.
There is absolutely no wind on the Moon as attested by astronauts.
Therefore, due to no wind on the moon the footprints there won’t be disappeared.
Total of 79 known moons to our world which orbit the planet Jupiter. However, Planet Jupiter has moon which is the largest in the whole solar system.
Ganymede, is the largest moon in our solar system. Also it is 33,729 miles (Approx. 5.262 km) in diameter. Therefore, the size of this planet is greater than the planet mercury.
The planet Mercury revolves around the sun at a slower rate.
Therefore, planet Mars has a longer day than Earth. However, Planet Mars has a total of 687 days.
Earth completes its single rotation in 24 hours.
However, the sun takes around 25- 35 complete days of our earth to make a single rotation
- Earth got its name from mixing up both Old English and Old Germanic words for “Ground”.
Planet Pluto is smaller than United States. However, United States is around 4650 km in size. Also planet Pluto is 2374 km in size.
Therefore, the equator of the planet Pluto would be the same distance as distance from London to Denver (around 56 miles).
Most of the volcanoes of planet Venus are probably long extinct.
However, planet Venus has a total of more than 1600 major volcanoes on its surface. Also, volcano of 5 miles in size (8 km) appeared there. The name of the volcano is Maat Mons.
The gases like Hydrogen, Helium and Methane are present in the atmosphere of the planet Uranus.
The methane gas present in the uppermost atmosphere of planet Uranus separates the red light coming from the Sun. However, reflects the blue light in the space. This give a really beautiful blue colour appearance to the plant Uranus.
There are total of 4 planets in our solar system, which are known as Gas Giants.
Jupiter, Saturn, Uranus as well as Neptune are the 4 planets. However, gases like Hydrogen and Helium are compressed in this Gas Giants.
There are a total of 5 larger moons as well as 22 smaller moons. Titania is the largest moon of the planet Uranus. It is the eight largest planet in our solar system
The size of this moon is approximately (1,578 km).
Till now Triton is the only largest Moon which orbits around the planet Neptune in the backward direction.
The astronomers have observed direction of the revolution of moon. But are not sure till now about why it orbits the Neptune in this direction.
- There is no sound in the space because there are no objects in the space. As the objects transmit sound but the objects here are far apart which results in no transmitting of the sound.
One million Earth can fit inside the sun. This is how much big the Sun is in size.
However, it is considered as an average sized star.
Planet Jupiter, Saturn, Uranus as well as Neptune have no solid surface. They contain mostly gases.
There are approximately 10 times more stars in the night sky than there is sand on the Earth. Also, 70 sextillion stars are visible in the night sky from the Earth with the help of a Telescope.
In numbers 70 sextillion is 70,000,000,000,000,000,000,000 which is really a large number.
Neptune revolves around the Sun at a very slow rate of about 5.43 km/sec. At this constant speed planet Neptune takes around 60,190 Earth days to complete a revolution around the sun.
Therefore, this means that Neptune has completed just 1 revolution till now.
Charon is the largest moon of the planet Pluto. It’s size is approximately half of the size of the planet Pluto itself.
The same surface of Charon as well as Pluto always face each other, known as mutual tidal locking.
On planet Earth this equates to about 6 Days 9 Hours and 36 Minutes. A day on the Pluto is so long because planet Pluto has a really slow rate of rotation.
This happens due to surface tension, which is the imbalance of the intermolecular attractive forces.
This can also occur in the lower orbit of the Earth.
68% of the universe consists of the dark energy as well as 27% consist of dark matter. However, both of these are invisible which equals to about 95% of the Universe.
Therefore, this means that we are able to see only 5% of the Universe.
Sun emits Photons which travel along the vacuum of the space at a speed of light. However, this takes around 8 minutes and 20 seconds to reach our eyes.
Planet Jupiter is large enough as well as it can hold up to 318 Earth inside it. However, the size of the Jupiter is approximately 139,820 km Also, Jupiter is the largest planet in the Solar System.
Uranus, ranked at the seventh position from the sun. However, this planet is the coldest of all. Also, this is because of the tilt of the Planet Uranus.
Therefore, due to this tilt Uranus spills out most of the heat and retain a very little.
As a result, this makes the planet the most coolest planet compared to others.
International Astronomical Union (IAU) uses a three condition criteria to define a full sized planet.
However, the Pluto now considered as Dwarf planet as it did not meet the conditions.
Also, it is the ninth largest planet as well as tenth most massive object revolving directly around the sun.
The planet Uranus, the first planet discovered through the telescope, discovered in the year 1781. This expanded the known limits of our solar system.
Mercury, Venus, Mars, Jupiter as well as Saturn are bright enough that they are easily visible through naked eye.Also, we can see them in the pre- dawn sky.
Therefore, we only need clear skies as well as our bare eyes to watch them all without any instruments.
Saturn is the second largest as well as sixth planet from the sun.
However, it’s average radius id almost 9 times that of our Earth.
In Solar System there are a total of 4 Inner Planets. Also known as inner planets on basis of their distance from Sun as well as they are rockier.
Therefore, Mercury, Venus, Earth and Mars are the 4 Inner Planets.
Turns out true because oceans cover almost 70% of our Planet.
While we have covered 100% of Mars Surface.
If we are driving at 75 miles per hour, then it will take around 258 days to complete a round on Saturn ring.
Also, they are around 175,000 miles long and 3200 feet thick.
Shortest distance between Earth as well as Space is 61 miles (100 km).
Therefore, after 100 km boundary of Earth ends.
ISS orbits Earth every 90 minutes at a speed of 17,100 miles per hour.
Therefore, ISS orbits 16 times around the Earth per day.
The Galaxies are classified by their shape. Therefore, there are 3 general types of galaxies which are elliptical, spiral and irregular.
However, most familiar kind of galaxies are spiral galaxies.
Stars, not randomly scattered in the space. However, gathered in vast groups called as Galaxies.
Also, our Sun belongs to a Galaxy known as the Milky Way. Astronomers say that there are 100 thousand million stars in the Milky Way only.
But there are millions of galaxies out there other than milky way which contains stars.
We can see a total of 9 different galaxies from Earth with naked eye by putting efforts.
Andromeda galaxy is the closes galaxy from the Earth.
Also, the accurate distance of the Andromeda galaxy from the earth is 2.537 million light years
Know what light year is in the Fact no 7 above.
Powehi was captured with the Event Horizon Telescope. It is a project that connected 8 telescopes around the world.
A super massive black hole as well as it was found in the center of the galaxy known as M87.
The astronomical unit is the unit of the length. For example, it is a unit of measurement which is equal to 149.6 million km.
However, this is the distance from the center of our Erth to the center of the Sun.
Venus is a planet which is choked with sulphuric acid. Therefore, it snows sulphuric acid.
The first spacecraft to visit mercury was Mariner 10. Also, it covered almost 45% of the surface of Mercury.
Even when you scream no one can hear you. Because there is no air in the space and it is a vacuum.
The shell of the air ends around 100 km above the Earth.
Space agencies officials made sure that Coca-Cola was advertised about with full-page ads in papers around the country that proclaimed: “The first soft drink enjoyed in space was a Coke. Obviously.”
Astronauts when in space can grow up to 3% tall during the time spent living in micro gravity, NASA scientists attested.
This means that a 6-foot-tall (1.8 meters) person could gain as many as 2 inches (5 centimeters) while in orbit.
The shape of the Kuiper Belt is doughnut shaped ring made of icy objects around the whole sun, extending just besides the orbit of Neptune from about 30 to AU.

She is the first ever women to go visit space, Launched into space on Vostok 6 mission in the year 1963.
She has spent almost 3 complete earth days in the space as well as she orbited our Earth 48 times.
Saturn Rings are very thin because they are made up of Dust Grains to Boulders.
Also, if Saturn ring were 3 feet long they would be 10,000 times thinner in size than razor blade
Hubble Space Telescope can see up to 10 -15 light years far.
However, when the telescope was launched it cost around US $4.7 Billion. Also, this Telescope was launched back in the year April 24, 1990.
Exoplanets are the planets which revolve around other stars in the Galaxies.
They are hard to see with the telescope because of the bright glare of the stars around which they orbit.
In reality, the gravity of the moon drag our earth which slows down its rotation.
However, the moon is moving away from Earth due to the tidal locking between the Earth and Moon.
Pluto is the only world so far which is named by a 11 year old girl.
Also, the name of the girl is Venetia Burney who lives in Oxford, England.
This name of the Pluto comes from the Roman God of underworld which she suggested to his grandfather firstly.
If we assume we have a clear night sky we can surely see ISS.
However, for us it looks like a bright star moving from the horizon the horizon.
However, the Saturn is completely made up of gases, yes it can float on water. Also, atmosphere of Saturn is windier.
Therefore, Saturn will require a large amount of water since it is second largest planet in our Solar System.
George is better called as Uranus. Astronomer William Herschel discovered this planet in the year 1781.
Also, he named the planet in the honour of his patron King George.
However, the planet was seen many times before but was recognized as a star. Because it is far away from the sun that it appears like a star.
The sunsets on Mars would seem blue in colour to human observers on Mars.
However, the actual reason is that the dust particles on the Mars always make a blue glare around sun. Therefore, when the light passes through all the dust while moving from horizon the sunset appears blue in colour.
Here, the mass of our Earth is 81 times more than the mass of Moon.
However, the distance between both of them is 60 times the radius of the Earth.
Laika was a mixed- breed dog. Also, she was launched in space in the year 1957 in Soviet Union Sputnik 2.
But sadly Laika died after 4 days in the space orbit due to the overheating of the cabin.
It is a U.S government agency responsible for the science as well as technology related to space.
They launched their first spacecraft in 1957 in space.
He is a Russian Air Force Officer as well as an RKA cosmonaut.
Also, he holds a world record of most days spent in space of 879 days.
The atmosphere on our Earth is almost 300 miles thick.
However, Mercury has a very thin layer of atmosphere that it barely exists. Also, mercury has the thinnest layer of atmosphere compared to all the other planets.
Milky Way is also known as the ‘Silver River’. Also, it is known as the ‘River of the Heaven’.
However, this name mostly seems across East Asian Languages.
The lower the mass of the Red Dwarf Planet the longer is its lifespan.
However, the Red Dwarf Planet can survive more than the expected 10 billion years lifespan of our sun. Therefore, the these planets can burn for a total of almost 10 trillion years.
Jupiter has the most insane gravitational pull as compared to all other planets in our Solar System. This is because it is the most massive planet in our whole Solar System.
However, the gravity on the surface of the Jupiter is 2.5 times more than Earth.
Mercury requires approximately 58.6 Earth days to rotate on its axis. Therefore, it takes around 58 Earth days to experience a single day on planet Mars.
Also, there is only 1 sunrise and 1 sunset during this 58 days.
Most of our pens depends on gravity. Therefore, while writing the gravity pulls the ink in the ball.
However, this is not possible since there is a negligible amount of gravity in space.
Light travels at a speed of around 300,000 km per second. Therefore, light takes around 1.3 seconds to fall on Earth from Moon.
For instance, Moon is 1.3 light seconds away from our Earth.
In 1922, IAU accepted the latest list of the 88 star constellations.
However, in 1928 it adopted legal constellation boundaries which together cover the whole celestial sphere.
Yes, Nucleus is the solid central part of a Comet. However, comet is once also called Dirty Snowball and Icy Dirtball.
As per 2014, IAU attested five dwarf planets. Therefore, Ceres, Pluto, Eris, Haumea as well as Makemake are the 5 dwarf planets.
After more than thousands of trips around Earth, Buzz Lightyear landed at Smithsonian.
Also, he flew to the space in May 31, 2008.
lYes, the approx. Temperature in the empty space between celestial bodies is calculated as 3 Kelvin (minus 270.15° C or minus 457.87° Fahrenheit).
However, the temperature at which all of the activity stops is 0 Kelvin.
On average, there are almost 0.3 atoms per cubic meter in space.
Voyager 2, the only spacecraft launched by NASA in the year 1986.
Also, this spacecraft is the only one to ever visit planet Uranus as well as Neptune. However, it visited these respective planets in the year 1986 and 1989.
Planet Jupiter is the only fastest planet in our whole Solar System. Also, it takes only less than 10 hours for rotating.
However, considering the size of the Jupiter it rotates really faster than any other planet. Therefore, Jupiter has the shortest day of all the planets known till now.
Exactly, Jupiter takes almost 11.8 year to make a complete revolution around the sun.
Therefore, this means that a year on Jupiter is around 11.8 Earth years.
Jupiter’s insane atmosphere, mostly made up of hydrogen and helium.
However, it has 3 layers of compressed hydrogen gas, liquid metallic hydrogen and core of ice, rock and metals.
This red spot raged for around 350 years.
However, it is very large that almost 3 Earth’s could fit inside it.
Earth is the densest planet in our Solar System.
But, if we do consider the gravitational compression then Mercury will be at the 1st place.
It is the 4th largest planet if we consider in the terms of diameter. But, it is the smallest if we compare it to Gas Giants.
The name is an excellent choice because Neptune is the name of the Roman God of the Sea.
Also, this explains the blue colour of the Neptune. However, in Greek mythology it is known as Poseidon.
It is Gas Giant as well as it is farthest from sun still the climate is very active on it. Also, one of the largest storms ever recorded was in year 1989 on Neptune.
A single day on Uranus takes about 17 hours. However, it takes around 84 Earth years to complete a single revolution around Sun.
LTherefore, this comes out as 30,647 Earth days.
The polar diameter of Saturn is 90% of its equatorial diameter. Also, this is because of its low density and fast rotation.
One day on Saturn takes around 10.7 hours only as well as Saturn takes around 29.4 years to make a complete revolution around sun.
Also, this means like our Earth Saturn also experiences Seasons.
Most of the part of Saturn, composed of hydrogen which it captured during the stage of its formation. However, the remaining part mainly consists of helium, methane as well as ammonia.
Yes exactly, Saturn has 150 moons and moonlets in all. However, only 62 of them has confirmed orbits. Also, only 53 of them have given official names.
Four robotic spacecraft have visited Saturn till now. NASA’s pioneer 11 provided the first ever close look in the year 1979.
If compared, Mars is almost half the diameter of our Earth. However, the surface of planet Mars is approximately same area as Earth’s dry land.
In the year 2018, the largest dust storm is recorded which circled the whole Martian globe.
Also, it was so thick that it hid the surface from the sun as well as killed Opportunity rover.
As of year 2019, 266 meteorites have been specifically identified as Martian.
The red planet, Mars is named after the Roman God of War. This is because its reddish colour reminds of Blood.
Venus is roughly around the same size of our Earth.
However, Venus is slightly smaller.Planet Venus is located 0.7 au away from sun.
Venus is a special case because it has dense atmosphere which acts as a greenhouse. Therefore, it heats the surface of Venus over the melting point of Lead.
It comes out as 880 Degrees Fahrenheit (471 degree celsius)
Venera 13, a Soviet spacecraft, the 1st spacecraft which landed to transmit colour images from surface of Venus.
Mercury revolves around the sun every 88 days.
Therefore, a year on mercury is almost 88 Earth days.But a single day on Mercury is about 59 Earth days long.
After our Earth, Mercury comes out as the second densest planet in our whole Solar System.
However, Mercury has a huge metallic core with a radius of almost 1,289 miles.
Mercury is the closest planet to the sun therefore it gets direct insane heat. Also, still it is not the hottest planet in our solar system it comes after Venus.
Out of the both, Mariner was the first to study both Venus as well as Mercury in the year 1974.
Moon is moving away while spinning at a speed of 3.78 cm per year. This is because of the tides of our Earth.
As the moon has less mass as compared to our Earth it will not pull us at what force Earth does.
Therefore, even though your weight is the same you may weigh much less on moon.
Pluto’s surface, mainly covered with ices as well as different mountain ranges.
Pluto is so small that it is only half the size of United States.
Also, Pluto is smaller in size than moon of our Earth. However, Pluto takes around 248 Earth Years to revolve around the sun.
It is calculated that hundreds of millions of pieces of space trash as well as these trash are floating in the space.
