How many light years are in a earth year?

Answer 1

An Earth year is a measure of the time it takes for the earth to make one complete orbit of the sun. So this is actually a unit of time.

A light year is the distance light will travel in one Earth year. So this is a unit of distance.

So the two units are not comparable for the reasons of this question.
A light-year is a unit of distance, not time. It's the distance light travels in one year.
A light year is a measure of distance, not a time. It's the distance that light travels through vacuum in one year.
An Earth year is a measurement of time, i.e., approximately 365.25 Earth days. A light year is a measurement of distance, i.e., the distance that light travels in a year. As such, the two cannot be compared with one another.
A light year is a measurement of distance where as one Earth year is a measurement of time.

1 light year is the distance a photon of light travels in 1 Earth year which is about 9,460.5 billion km.

Answer 2

None. Even though the two terms sound as if they're two forms of the same thing,

they're not.

A "year" is a period of time. It's the time between two of the same person's birthdays,

the time between two consecutive New Year's Eves, and the time it takes the earth

to complete one orbital trip around the sun.

A "light year" is not a p[eriod of time. It's a measure of distance. It's the distance that

light travels through space in one year. It's an enormous distance, but it doesn't even

get you to the nearest star outside our solar system.

In units that we can understand, one light year is roughly 5,878,500,000,000 miles.

You can see why it's a lot easier to talk about light years than miles when you need to

describe distances in space.
