# Write a few points on Milky Way.

ANS:


* The galaxy in which our solar system is situated is called the Milky Way. Milky Way appears as a milky belt stretching from North to South during dark night when the sky is clear.
* Milky Way is spiral in shape when viewed from the top. When viewed from the sides, it is seen bulging at the center and tapered towards the ends.
* The diameter of Milky Way is about 1 lakh (0.1 million) light years and the thickness of the middle (bulging) part is about 15000-20000 light years.
* Sun (and therefore the solar system)is located at about 30000 light years away from the galactic center.
* The sun completes one revolution around the galactic center in 22.5 crore (225 million) years at the speed of 250 km/s.
