What does 6300 light years equal to in earth years?
A light year is a unit of distance, not time. It represents the distance that light travels in one year. So 6300 light years is the distance that light would travel in 6300 years on Earth.
Is a light year measured in distance?
Not really. A light year is a measure of distance. It is the distance light can travel in one earth year, about 6 trillion miles
