`M = (1.98855±0.00025)×1030 kg`

1.98855E+30

The solar mass (M_?) is our standard unit of mass for estimating the mass of massive bodies near to or greater in mass to our solar system's Sun.  A solar mass is equal to approximately 1.99 × 10³⁰  kilograms.

A solar mass is used to represent the estimated mass of very large bodies or objects such as stars and galaxies.

A solar mass is equal to the mass of our solar system's Sun, which is about two nonillion  kilograms.

M_? = 1.98855×10³⁰ kg
