Galaxy:-Full of Mysteries
Our Galaxy is most unknown place for humans. If we try our best then also we can not explore the only 1% of the Universe. We all know that name of our galaxy is Milky Way . I am going to tell some facts about it and give some information about Galaxy .
1.Do you know that 12 earth can be fit in an sun which means sun is 12 times bigger than earth and 2 Sun can be fit in a Jupiter which means Jupiter is almost 2 times the sun .
2. There is only one star in our Milky Way Galaxy that is Sun . And the Sun is the brightest object in our galaxy .
3.The stars you look up at the sky have a little brightness as looking from here but some of the stars are more brighter and warmer than sun .
4. When we take a care and drive it straight up to sky at the speed of 60 km/hr . It will take 500 years to reach the Jupiter . So , You can imagine how fast the Rocket moves.
5.When Astronauts go to the space they plant an algae which don't need oxygen to grow and provide an good number of oxygen.
6. Sunita Williams was the first woman who stayed 6 months in space and then returned .
7.If you throw a ball in the space then it will never stop moving as there is no gravity in space and no external force to stop it.
8.The nearest galaxy to Milky Way Galaxy is Andromeda and if it smashed to Milky Way Galaxy then it will form a huge galaxy .
9.If all helium is over in the space then The Sun will become White dwarf . But this incident need atleast 5 billion years .
10.Right now the sun's temperature is around 5,000 .C . And if the helium ended in the Galaxy than the sun's temperature will be -6,900.C .
