Question

The distance of the celestial bodies is measured in light years. Why ?

Answer 1

The light year is used to measure distances in space because the distances are so big that a large unit of distance is required.

Step-by-step-explanation:

• Since many celestial objects, such as galaxies or stars, are extremely far from the earth, it is highly awkward to give their distances in kilometers.

• A light-year is a big unit that measures how far light can travel in a year. As a result, the great distances are measured in light-years.

• Light years are 9.46 x 1012 kilometers.

• A star's distance from the earth is measured in terms of how long it would take light to travel between it and the star, so if a star is eight light-years away, the light would travel that distance in eight years.

• The separation between the earth and the star is therefore equal to 8 (9.46 1012) = 7.6 1013 km.
