Class M Stars are the most common type of stars in the galaxy, composing about 76% of the main sequence stars in our region of the galaxy. They are the next category colder than a Class K Star, and burn red as a result. Class M stars come in a variety of sizes and specifications:

• M V Stars, also known as Red Dwarfs.
• Giant stars, Supergiants, and Hypergiants. See also Red Giant Star.
• Mira Variables
• Flare Stars
• The hottest of the Brown Dwarfs. (The less energetic of the Brown Dwarfs are Class T Stars, or arguably not even stars at all.)

Chemically, red stars have less Hydrogen than other stars. In it's place are more complex molecules, such as Titanium Oxide, Vanadium Oxide, and various other Neutral Metals.
