A light year is a unit of?

Answer 1

The distance light can travel in one year. It is used by astronomers. It is calculated by this formula. Good luck. The speed of light is 186,000 miles per second. A light year is:

186,000 miles per second x 60 seconds in a minute x 60 minutes in an hour x 24 hours in a day x 365 days in a year

186,000x60x60x24x365=

It is a unit of measurement of speed based on light.

Answer 2

No, it is more accurately a unit of length. It is the distance light travels in one year (in a vacuum). Since light travels at about 186,282 miles every second, in one year's time it will have traveled about 6 trillion miles.

Answer 3

No. a light-year is the distance that light will travel in a year in a perfectly straight line, therefore a distance. It is used for measuring how far away distant bodies are, usually stars. For all practical purposes, a light-year is 6 trillion (6,000,000,000,000) miles. A scientist could give you a more precise answer, but I suspect this is good enough.

Answer 4

No a light year is the distance that light travels in a year, 9.5 million million kilometers. Normally astromoners use light year to measure distances between stars.

Answer 5

Light year is a unit of distance. It is the distance light travels in a year.
