Never heard of ostranamas, but astronomers use light years to measure distances in space. A light year is the distance that light can travel (in a vacuum( in a year and is slightly less than 2.4 trillion kilometres.
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.
No. A light year is a measure of distance. It is the distance light travels in a year.
No. A light year is a measure of distance, not time. It is how far light travels in a year.
A light-year is a measure of distance, not time as many people mistakenly believe. One light-year is the distance light can travel in one year in the vacuum of space. One light-year equates to 5.8785 trillion miles.
Well... yes, but it's not a very useful one. Light travels one light year in... one year. So the speed of light (which you cannot accelerate to) is about 1/8766 light years per hour.
light year the DISTANCE light travels in a year so 'light year' is not a measure of time.
A light year is the distance that light travels in a year. We use it because it allows us to measure huge distances.
The light-year is a measure of distance. It's the distance light travels in vacuum in one year. 5.8787 x 1012 miles (rounded)
None. A light year is a measure of distance, not of time.
None. A light year is a measure of distance, not of time.
No. A light year measures such large distances that it would be highly impractical to measure anything on Earth. The light year is used to measure distance in space beyond the solar system.
A light year is actually a measure of distance. it's the distance that light travels in one earth-year. A year is a measurement of time equal to the amount of time that it takes the earth to go around the sun once.
