How many Earth years equals .2 light years?

Answer 1

Light-years are not a measure of time. Light-years are a measure of distance, the distance that light travels in a year. This measurement is used to measure the distance between stellar objects like galaxies, stars, and sometimes planets.

Answer 2

A light year is the distance that light can travel in a calendar year.

So, they are related, but they can't really be compared as time or distance, because a year is time and a light year is distance. A light year is almost 6 trillion miles, and a regular year is 365 days. (366 during leap year.)

Answer 3

1 'year' is a length of time. It's roughly the same as 365 days, 52 weeks, 12 months,

or the length of time you have to wait between two birthdays.

1 'light year' is a distance. It's the distance that light travels in one year of time. That's

a distance of roughly 5,878,700,000,000 miles.

And now you know why the "light year" was invented ... it's a lot easier to say "one light year"

than it is to say "5,878,700,000,000 miles".

Answer 4

A light year is not a measurement of time but rather of distance. It is the distance that light (travelling at 3x108m/s) would cover in a year. This is approximately 9.45x1015 m.

________________________

To calculate the length of a light year;

Light travels at 300,000 km per second, or 186,000 miles per second.

There are 60 seconds in a minute, 60 minutes in an hour, 24 hours in a day and 365.25 days in a year. Just multiply all those numbers together.

Answer 5

A light year is a measure of distance. The only equivalence between the two is that a light year is equal in length of time to an Earth year.

Answer 6

A light-year is the measure of the distance light travels in the vacuum of space during one Earth year; it is not a measure of time so cannot be compared to a year on Earth.

Answer 7

A light year is a measure of distance, not time. It is the distance that light travels in one year, about 5.9 trillion miles or 9.5 trillion kilometers.

Answer 8

A light year is a distance not a length of time. It measures the distance that light travels in one earth year.

Answer 9

a light year is not a measurement of time but a measurment of the distance light covers in a earth year.

Answer 10

A light year is a measure of distance, not time.
