The Milky Way belongs to a group of around forty galaxies called the Local Group. It has a mass of 1012 solar masses and an average diameter of about 100,000 light years. The solar system is the set formed by the Sun and the eight planets with their respective satellites that rotate around them.
Keeping this in mind, the universe contains galaxies and galaxies contain systems.
Therefore, the correct sequence from least total mass to greatest total mass is:
A. Solar System, Milky Way , Universe
