The galaxy that contains our solar system is known as the Milky Way Galaxy. It is a barred spiral galaxy, which is part of a larger group of galaxies called the Local Group. The Milky Way has a diameter of about 100,000 light-years and is estimated to contain 100 to 400 billion stars, along with a significant amount of gas, dust, and dark matter.

This galaxy is characterized by its spiral arms that radiate outwards from the dense center, where the majority of the galaxy's mass is concentrated, including a supermassive black hole called Sagittarius A*. The solar system is located in one of the spiral arms, known as the Orion Arm, situated roughly 26,000 light-years from the galactic center. This proximity allows for the conditions necessary for life on Earth, as the solar system is located in a stable region of the Milky Way with a relatively low density of stars nearby, reducing threats from supernovae and other cosmic events.

The other galaxies listed—Andromeda, Sombrero, and Whirlpool—are distinct and separate from the Milky Way. Andromeda is the nearest spiral galaxy to the Milky Way and is on a collision course with it, while the Sombr
