1) SATURN WOULD FLOAT IN WATER
Hypothetically, Saturn’s less dense than water which means that if put in a very large bowl of water, it would float.
2) THE FOOTPRINTS ON THE MOON WILL BE THERE FOR MILLIONS OF YEARS
The Moon has no atmosphere, which means there is no wind to erode the surface and no water to wash the footprints away. This means the footprints of astronauts, along with spacecraft prints will be there for millions of years.
3) THE MOON WAS ONCE A PIECE OF EARTH
Earth was struck by a giant object and this collision broke a piece of the Earth away to create the moon. It then began to orbit the Earth as a result of its gravitational pull.
4) MARS ALSO HAS WATER
For years it was believed that Earth was the only planet in our solar system with liquid water. More recently, NASA revealed its strongest evidence yet that there is intermittent running water on Mars, too!
5) SPACE IS COMPLETELY SILENT
There is no atmosphere in space, which means that sound has no medium or way to travel to be heard.
6) ONE DAY ON VENUS IS LONGER THAN ONE YEAR
Venus has a slow axis rotation which takes 243 Earth days to complete its day.
7) SUN MAKES UP 99.8 PERCENT OF SOLAR SYSTEM'S MASS
The sun is so large that it would fit one million planet Earth inside of it. It makes up 99.8 percent of our entire solar system’s mass.
8) THERE IS FLOATING WATER IN SPACE
Astronomers have found a massive water vapor cloud which holds 140 trillion times the mass of water in the Earth’s oceans somewhere around 10 billion light years away – making it the largest discovery of water ever found.
