How far are stars from earth?
· Our sun is the nearest star to Earth. After the sun, the next nearest star is 4.3 light years away.
· A light year is the distance light travels in one year. One light year is 10 trillion kilometres. That's a HUGE number! Here's a way to imagine how far it is: to travel 10 trillion kilometres, you would have to circle the whole Earth 233 million times.
· The star closest to the Earth is, of course, the Sun which is about 93 million miles away or 500 light seconds
