It is impractical to measure distances within solar system in Light Years because a Light Year is too big unit for solar system. Distances within solar systems are measured in Astronomical Unit. Accurately and precisely an Astronomical Unit (AU) is equal to 149,597,870,700 metres. This is the the approximate mean distance between the Sun and the Earth.
