A light-year is the distance light can travel in one year. Light travels at 186,000 miles per second. Multiply that by 3600 seconds in an hour and then by 24 hours in a day and 365 days in a year and you will get the distance in one light-year.
A light year is defined as 9,460,730,472,580,800 meters exactly, derived
from the distance that light travels in vacuum in one Julian year.
A light year is simply the distance that light travels in 1 year.
About 9.47x10^15 metres
A light year is a year.
That's the approximate length of a light-year - the distance that light travels in a year.
Because in normal units the numbers are too . . . astronomical. At 299,979 km per second, light travels 1 light year in one Julian year, 365.25 days. So quite a long distance. Earth is 8 light-seconds from the Sun, the nearest star is just over 4 light years away.
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 can travel about 6 trillion miles in a year, so that distance is called a light-year.
A light year is a unit of space, not time. It is the distance light travels in a year. Eris is far less than a light year away.
A light year is a measure of how far light can travel in one year. It is a phenomenal distance, and is used to describe how far away stars are from us.
Using light years, which means the distance light travels in a year.
A light year is a measure of distance and is the distance light travels in one year's time. The light year is used to describe the enormous distances between various objects in space. In one year, light travels about 6 trillion miles.
A light-year is a measure of distance that a photon of light will travel in one year .
1 light year = 9.4605284 × 1024 nanometres
1905 was important because in that year he made his scientific theories that describe about light
The question should be How Long is a light year (in standard form) as a light year is the DISTANCE that light will travel in one year No...I'm not sure what a light year would be in a leap year.
1 year A light year is the distance light travels in 1 human year One light year is 186000 X 60 X 60 X 24 X 365 miles
One year.
That's the approximate length of a light-year - the distance that light travels in a year.
A light year is the distance light travels in a vacuum (such as space) in one year's time. It is equal to 5,878,499,562,554.681 miles or 9,460,528,000,000 kilometers.
The correct unit to describe the distance between stars is the "light year", the distance a photon of light would travel (through a vacuum) in a year.
