Sun or Solar Mass
Sun or Solar Mass :
A unit of mass used in astronomy to express the masses of stars. Stars are so massive that it's difficult to grasp their relative sizes. Using the Sun's mass as a unit helps us visualize them relative to something familiar. The best current estimate of the mass of the Sun is 1.9891 x 1030 kilograms or 1.9891 x 1027 tonnes; this is about 1048 times the mass of Jupiter and about 332 900 times the mass of the Earth
