... What is the distance from the earth ? There are different ways of measuring interstellar distances. A light year is the distance that light travels in one year. In light years, Alpha Centuri is 4.2 light years away. The speed of light is about 3 x 10 to the 8th power m/s or 186 000 miles per second. ...
