FAQ
How can you locate the Pole Star using the Saptarishi (Big Dipper) constellation?
Look at the two stars at the end of the Big Dipper’s bowl and extend an imaginary straight line through them towards the north; at about five times the distance between those two stars lies the Pole Star (Polaris).
What is the order of the eight planets from the Sun?
In order of increasing distance from the Sun, the eight planets are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune.
