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

0.2 light years is equal to approximately 1.89 trillion kilometers. At the speed of light, this distance would take around 1.89 trillion seconds to travel. This is roughly equivalent to 59,900 Earth years.

Answer 3

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 4

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 5

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 6

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 7

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 8

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 9

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

Answer 10

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