Answer 1

Answer:

the distance between celestial bodies is measured in a unit is called light year

Answer 2

Answer:

The universe is vast and their are so many cosmic objects and the normal unit which is used to measure normal objects cannot be useful on measuring celestial bodies so the following measuring units are invented,

ASTRONOMICAL UNIT(AU):

                          It is used to measure the distance within our solar system. one au is equal to the distance from center if sun to earth's orbit

LIGHT YEAR:

                     It is the time taken for the light to travel one year in space

                  1 light year = $9.462*10^{15}$

PARSECS:

              When the number of light year is comparatively higher and can't be measured then parsecs is used for measurement

                     1 parsecs = 3.26 light years

the astronomer's uses megaparsecs for measuring intergalactic distances.
