Physics Notation Help: M_\odot - Mass?

In summary, M<sub>o</sub> represents the standard unit of mass known as a solar mass in physics notation. It is calculated by using the mass of the Sun as a reference point and is a widely accepted unit of measurement in astrophysics and cosmology. M<sub>o</sub> can be used to measure the mass of any celestial object, including planets, galaxies, and black holes. It is a fixed value that is used as a standard unit of mass, but may vary slightly in different contexts.
