8.2: Velocities, Mass, and Gravity

Despite having nearly all the mass in the solar system, the sun is relatively tiny in extent; the diameter of the Sun is much, much smaller than the distances between the planets and the Sun. Given these circumstances, we may model the Solar System''s mass distribution very simply. To high precision, we can assume that all the mass in the

What is the mass of the sun?

This value is astronomically large and is essential for understanding the immense gravitational influence the Sun has over the solar system. In scientific notation, the Sun''s mass is denoted as M☉.

Meet the Sun

Earth and all other objects in our solar system orbit around the Sun due to gravity – the Sun contains over 98% of all mass in the solar system and so exerts a strong gravitational pull. Like other stars, the Sun is a dense ball of gas that creates energy through nuclear fusion reactions in the core, creating helium atoms from hydrogen atoms.
