2.Interesting Scientific Facts About Space:

1. The Sun is more than 3,00,000 (3 lakh) times larger than the size of the Earth, which means 1 million Earths could fit inside the sun.
2. Space is absolutely silent as there’s no atmosphere for sound to travel through!
3. It isn’t possible to walk on planets like Jupiter, Neptune, Saturn, or Uranus as they don’t have a solid surface! They’re mostly made up of different gases.
4. The moon doesn’t emit any light of its own. The light from the sun’s rays bounce off of the moon and reach the Earth in a matter of 1.25 seconds. This is how we get moonlight.
5. No life form can survive if they were to enter a black hole, like the one at the centre of our galaxy, the Milky Way. Even light can’t survive in a black hole.
6. The reason the ocean has waves and has tides that switch from high to low is that the gravitational pull from the moon and the sun keep changing.
7. Do you know what the highest mountain known to man is? If you said Mount Everest, you’re only partially correct. Mount Everest is the highest mountain on Earth, but the highest mountain known to man is actually present on an asteroid called Vesta and is 22km in height: thrice as big as Everest
8. There are more stars in the universe than there are grains of sand on Earth.
9. Neil Armstrong was the first man to walk on the moon in 1969.
10. Did you know that you can still see traces of his footprints on the moon’s surface? This is because there’s no wind on the moon, and so the footprints and tire tracks are still pretty intact!
11. It is believed that there are between 200-400 billion stars just in the Milky Way galaxy, of which our solar system is a very, very tiny part. In the observable universe, there are about 100 billion galaxies like the Milky Way. There could be around 100 billion Earth-like planets in our galaxy alone! 
12. It takes the light from the Sun about 8 minutes to reach Earth.

Little Known Facts About Earth:

Now that we’ve learnt a lot about outer space, let’s learn some unbelievable science facts about our Mother Earth!

1. About 70% of the Earth’s surface is covered in water.
2. The earth has been around for around four to five billion years, and the fascinating thing is that humans have only been around for between 0.1 – 0.2% of the time that Earth has existed!
3. Earth is the third planet from the Sun and is the fifth largest planet in our solar system, after Jupiter, Saturn, Uranus, and Neptune.
4. Earth’s largest and only natural satellite is the moon!
5. Earth is the only planet in our solar system known to support life.
6. The Great Barrier Reef in Australia is known to be the largest living structure on Earth. It spans about 2,000 kilometres and is composed of coral islands and reefs.
