Solar mass

The solar mass (M☉) is a standard unit of mass in astronomy, equal to approximately 2×1030 kg. It is often used to indicate the masses of other stars, as well as stellar clusters, nebulae, galaxies and black holes. It is approximately equal to the mass of the Sun. This equates to about two nonillion (short scale) or two quintillion (long scale) kilograms:

M☉ = (1.98847±0.00007)×1030 kgThe solar mass is about 333000 times the mass of Earth (M⊕), or 1047 times the mass of Jupiter (MJ).
