The Milky Way – Our home galaxy

There are about 100 billion stars in our galaxy. We can see about 4000 on a typical clear, dark night.

Light Year

Light travels at NOTE :

A light year is The distance light travels in 1 year

This is equal to 9,460,730,472,580,800 meters (exactly)≈ 5,878,625 million miles ≈ 63,241.1 astronomical units
