A light year is a meausre if distance: the distance that light - or any other electromagnetic radiation - would travel in vacuum over a period of one year.
1 light year (ly) = 9.46073*10^15 metres (approx 5.9 trillion miles).
They don't. Light years are a distance measurement, not a time measurement.
A light year is a measurement of distance. It is the distance that light travels in a year. It usually measure the distance of things in space. One light year is about 5,869,713,600,000 miles or about 9,445,950,434,502 kilometres.
You cannot 'measure' light. However, there is the light-year, a measurement of the distance light can travel in one year. there are many. Lumens, cadlepower, foot candles and candelas. There are probably a few more.
No. A light-year is a measurement. A light year is a distance measurement based on how far light travels in a year.
The unit of measurement used to measure distances between galaxies is typically the light-year, which is the distance that light travels in one year. This unit is used because of the vast distances involved in intergalactic space.
A light-year is not a measure of time, but of distance: 5.87 x 1012 miles. The distance light could travel in one year. ______________________________________________________________________ one revolution of planet earth: one year. the question this should be is: how long is a light year- that answer i do not know A light year is a unit of distance equal to 5,865,696,000,000 miles
Light Year is unit for all astronomic distances
The unit of measurement is the "light year".
No. A light year is a measure of distance, not time; it is the distance that light travels in a year. So a cubic light year is a measure of volume, rather like a cubic foot or cubic meeter only much larger.
Astronomers commonly use the unit of measurement called a "light-year" to describe vast distances in space. One light-year is the distance that light travels in one year, approximately 5.88 trillion miles or 9.46 trillion kilometers.
Light-year is a physical measurement related to Universe Issues, and it comprises huge distances across the Universe. People's years is a measurement related to the lifespan, not only for humans but also for all living creatures. The difference is that People years is a measure only related to life, while light-years is not. The point is that a light year is a measure of distance NOT time. It does get people confused sometimes. It's how far light goes in a year.
