Light travels in a vacuum at 299,792,458 metres per second
As there are 365.25 days in a year, each of 24 hours, each of 60 minutes, each of 60 seconds, there are 60 x 60 x 24 x 365.25 seconds in a year .... 31,557,600 .... this gets us into two HUGE numbers.
A light year is officially defined as 9,460,730,472,580.8 kilometres or 9.461×1012 km
1 Light Year
Years are a measurement of time; light years are a measurement of distance. A light year is the distance light travels in one year (in a vacuum).
The light year was not discovered. It was made up, by people who kept coming up with distances like [ 25,866,280,000,000 miles ] in their work, and soon realized that they were going to need something bigger than a mile, so they invented the light-year.
In a vacuum, light will travel 299,792,458 meters in one second.
white light carries a long distance, especially at night. Using blue lenses on lights decreases the distance light can be seen, helping to conceal position.
A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles. A light year is a measure of distance, not time. A light year is the distance that light will travel in one year. One light second is 186,000 miles.
Light travels a distance of one light year in one year.
Only one. Because Light year is a messure of distance not of time. Light year is the distance travelled by light in one year.
The distance of one light year, in light years, is exactly 1.
'Light-year' is a unit of a distance. It is the distance for light to travel one year. So it is a great distance.
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
That's the distance light travels in one year - about 9.5 x 1012 kilometers.That's the distance light travels in one year - about 9.5 x 1012 kilometers.That's the distance light travels in one year - about 9.5 x 1012 kilometers.That's the distance light travels in one year - about 9.5 x 1012 kilometers.
A light year is a measure of distance, not time. A light year is the distance light travels in one year. In one day light travels 16,081,407,123 miles.
"Light year" is a distance. Specifically, it's the distance that light travels through vacuum in one year. The distance is approximately 5,878,291,000,000 miles.
1 Light Year
Light years is a measure of distance, not of time; it is the distance that light travels in one year.
One light year (the distance light travels in one year) is:5,878,625,373,000,000,000,000 miles.
