what is light year?
Answers
Answer:
the millions of years can travel the distance. the very long distance in the space
Explanation:
Light Year: A light-year is a unit of distance. It is the distance that light can travel in one year. Light moves at a velocity of about 300,000 kilometers (km) each second. So in one year, it can travel about 10 trillion km.
Distance in space is measured in light years as there can be very long distances and showing those distances in kilometers can be very confusing. so, light year is a unit to measure distances in space.
By saying that a star is 8 light years away from earth, the meaning is that a star is at the distance covered by light in 8 years from the earth
Light Year :- Distance travelled by the light in a year.
1 light year = 300,000*365*24*60*60 km
1 light year = 9.46* 10^12 km.
