Astronomical Unit (A.U)
It is evolved by radar
astronomy and is more accurate than the light year unit. It represents the mean
distance between the Sun and the Earth, calculated on the data supplied by
radars. The A.U. distance has now become a key constant in determining
distances in the solar system. A.6. is approximately 150 million (149.600.000)
km. It may be said that light year is made up of about 60.000 A.Us.
