M-type stars

M-type stars, also known as red dwarfs, are the most common type of star in the universe. They are smaller and cooler than our Sun, with surface temperatures ranging from about 2,400 to 3,700 degrees Celsius. These stars are characterized by their reddish color and relatively low brightness. Due to their long lifespans, often lasting billions of years, M-type stars are considered stable and can potentially harbor planets in their habitable zones. They play a crucial role in the search for extraterrestrial life, as many exoplanets have been discovered orbiting these stars.
