1. Core is the central part of the sun. Due to high temperature and pressure in the core,  it produces hydrogen gas to fuse helium. This process produces a large amount of energy from sun which is almost equivalent to a 100 billion nuclear bombs.

2. Moon has no weather, no wind and no air. If luckily, you get chance to visit moon, your footprints and presence will remain there forever.

3. There is a planet in the universe which is full of diamonds. Astronomers discovered this planet in 2004. It is commonly known as carbon planet or carbide planet.

4. One of the most amazing fact about space is cold welding. Cold welding is a rare way to bond two metals. In space when two metals touch each other, both of them are joined permanently with each other in such a way that they looks like one.

5. The rotation of our earth is getting slow by 0.001 to 0.002 seconds every century. Due to this slower rotation the length of the days are increasing.

6. Jupiter is the largest planet of Solar system. It is a big monster so it can hold all the planets.

7. If you can calculate one star per second then you can count all the stars in 3000 years.

8. There is no air in space so you can’t hear anyone even if he/she shouts in front of you.

9. The rotation of Pluto completes in 6 days and 9 hours approximately. So the length of Pluto’s day is equal to one week of Earth.

10. The bird’s can’t survive in space because they need gravitational force to swallow and there is no gravity in space.
