Â­So to measure really long distances, people use a unit called a light year. Light travels at 186,000 miles per second (300,000 kilometers per second). Therefore, a light second is 186,000 miles (300,000 kilometers).
So a light year is about (I've rounded off a bit) 5,878,786,100,000 miles. That's almost 6 trillion miles. The distance from the earth to the Sun is 93 million miles. The distance to the nearest star is 4.3 light years, and the distance to the Andromeda galaxy is 2 million light years.ating Newest Oldest. Best Answer: A light year is the distance that light travels in one year. The speed of light is 186,287.5 miles per second. You can find out the number of seconds in a year by multiplying the number of seconds in a minute (60) by the number of minutes in an hour (60).
