M-Type stars, also known as red dwarfs, are the smallest and coolest type of main-sequence stars. They have a surface temperature of less than 3,500 Kelvin and are characterized by their reddish hue. These stars are the most common in the universe, making up about 70-80% of all stars. Their low mass and temperature allow them to burn their hydrogen fuel very slowly, leading to long lifespans that can last billions of years. Due to their dimness, M-Type stars are often difficult to observe from Earth. However, they are of great interest in the search for exoplanets, particularly in the habitable zone, where conditions might support liquid water. Some of the closest stars to our solar system, such as Proxima Centauri, are M-Type stars, highlighting their significance in the study of stellar systems.
