Question

How many light year is the sun to the earth?

Answer 1

Not very many....

Explanation:

So one light year is `5.9*10^12` miles. The distance from the Sun to the Earth is 93,000,000 miles. With a little dimensional analysis...
`((1)/(5.9*10^12))*(9.3*10^7)` We get our answer of `1.58*10^-5`
