The commmonly used units in astronomy are

  1. Light Year - The distance traveled by light in one year. (300000 x 365 x 24x60x60 kms)
  2. Astronomical unit (AU) - The mean distance between sun and earth (approximately 300000x 8x60 kms)
  3. Parsec or parallactic second (1 parsec =3.26 LY)

Bigger distances are measured in MLy = Mega Light Year = 1000000 LY
