4.3light year is equais to how many earth years?

Answer 1

In spite of its name, a light year does not indicate time, but it indicates distance! It actually equates to the distance that light travels in one Earth year, which is a very big distance, seeing that light travels at 186,000 miles per second.

Answer 2

'Light years' is a measure of distance.

Earth Years is a measure of time.

'Light year' is the distance a photon of light will travel in one year.

Answer 3

A light year is the distance that light travels in one year, equivalent to about 9.461 trillion kilometers. It is not a measure of time, so it cannot be converted directly into Earth years.
