solar mass

(MSun, Msun)
(mass unit representing the mass of the Sun)

The unit, solar mass, the mass of the Sun, is commonly used as a unit of mass for astronomical objects. It is roughly 2 × 1030 kilograms, and 1.98847 × 1030 has been adopted as a standard value, a number reflecting reasonable determinations of the actual mass. Some example masses using the solar mass unit:

Body solar masses
Jupiter 0.00095
Neptune 5 × 10-5
Earth 3 × 10-6
Moon 3.69 × 10-8
O-type star main-sequence star 16 to 90
G-type star MS star 0.8 to 1.04
M-type star MS star 0.08 to 0.45
Taurus-Auriga Complex 35000
Milky Way 1.5 × 1012
Milky Way supermassive black hole 4.1 × 106
