why is the distance between stars expressed in light years? what do you understand by the statement that a star is eight years away from the earth

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

DISTANCE IS TOO LARGE TO EXPRESS IN KM. DISTANCE TRAVELLED BY LIGHT IN 1 YEAR IS CALLED A LIGHT YEAR. THIS MEANS THAT IT TAKES 8 YEARS FOR LIGHT TO TRAVEL FROM THAT STAR TO THE EARTH.

 The distance of the stars from the Earth and the distance between the stars are very large. It is inconvenient to express these distances in kilometer (km). Thus, these large distances are expressed in light years. One light year is the distance travelled by light in one year. One light year is equal to 9.46 × 10¹² km.

A star is located eight light years away from the Earth. This means that the distance between the star and the Earth is equivalent to the distance travelled by light in eight years, i.e., a star is located 8 × (9.46 × 10¹²) = 7.6 × 10¹³ km away from the Earth.

becoz distance is very large
