There is no atmosphere in space, which means that sound has no medium or way to travel to be heard.
2. THE HOTTEST PLANET IN OUR SOLAR SYSTEM IS 450° C.
Venus is the hottest planet in the solar system and has an average surface temperature of around 450° C. Did you know that Venus isn't the closest planet to the sun? That is Mercury. You would think that Mercury would then be the hottest, but Mercury has no atmosphere (which regulates temperature), resulting in big fluctuations.
3. A FULL NASA SPACE SUIT COSTS $12,000,000.
While the entire suit costs a cool $12m, 70% of that cost is for the backpack and control module. However, the space suits that NASA uses were built in 1974. If these were priced by today's pricing, they would cost an estimated 150 million dollars!
4. THE SUN’S MASS TAKES UP 99.86% OF THE SOLAR SYSTEM.
The Sun accounts for 99.86% of the mass in our solar system with a mass of around 330,000 times that of Earth. Did you know that the Sun is made up of mostly hydrogen (three quarters worth) with the rest of its mass attributed to helium. If the Sun had a voice would it be high and squeaky from all that helium?
5. ONE MILLION EARTHS CAN FIT INSIDE THE SUN
The Sun is large enough that approximately 1.3 million Earths could fit inside (if squashed in) or if the Earths retained their spherical shape then 960,000 would fit. But can you visualise that number of Earths?
6. THERE ARE MORE TREES ON EARTH THAN STARS IN THE MILKY WAY
There are about three trillion trees on Planet Earth, and between 100-400 billion stars, approximately, in the galaxy.
7. THE SUNSET ON MARS APPEARS BLUE
Just as colors are made more dramatic in sunsets on Earth, sunsets on Mars, according to NASA, would appear bluish to human observers watching from the red planet. Fine dust makes the blue near the Sun's part of the sky much more visibilke, while normal daylight makes the Red Planet's familiar rusty dust color the most perceptible to the human eye.
8. THERE ARE MORE STARS IN THE UNIVERSE THAN GRAINS OF SANDS ON EARTH
The universe extends far beyond our own galaxy, The Milky Way, which is why scientists can only estimate how many stars are in space. However, scientists estimate the universe contains approximately 1,000,000,000,000,000,000,000,000 stars, or a septillion. While no one can actually count every single grain of sand on the earth, the estimated total from researchers at the University of Hawaii, is somewhere around seven quintillion, five hundred quadrillion grains. That is an awfully big sand castle!
9. ONE DAY ON VENUS IS LONGER THAN ONE YEAR.
Venus has a slow axis rotation which takes 243 Earth days to complete its day. The orbit of Venus around the Sun is 225 Earth days, making a year on Venus 18 days less than a day on Venus.
10. THERE IS A PLANET MADE OF DIAMONDS
There’s a planet made of diamonds twice the size of earth The "super earth," aka 55 Cancri e, is most likely covered in graphite and diamond. Paying a visit to that planet would probably pay for the $12 million dollar space suit needed to get there!

Answer:1. SPACE IS COMPLETELY SILENT
There is no atmosphere in space, which means that sound has no medium or way to travel to be heard.

Answer:
here is the answer
Explanation:
Here are some interesting facts about astronomy:
The largest known star is UY Scuti, which is approximately 1,700 times larger than the sun.
The smallest known star is TRAPPIST-1, which is only slightly larger than Jupiter.
The nearest star to our solar system is Proxima Centauri, which is approximately 4.24 light-years away.
The Milky Way galaxy is thought to contain over 100 billion stars and at least that many planets.
There are over 100 billion galaxies in the observable universe, each with billions of stars.
A black hole is a region in space where the gravitational pull is so strong that nothing, not even light, can escape.
The age of the universe is estimated to be 13.8 billion years.
The sun is an average-sized star and will eventually run out of fuel in about 5 billion years.
Saturn is the least dense planet in our solar system and would float if placed in water.
The first exoplanet (a planet outside of our solar system) was discovered in 1995 and thousands have been discovered since.
These facts are just a small sample of the many amazing discoveries and wonders of astronomy.
