Here's why:
* Low Luminosity: Red dwarfs are the smallest and coolest type of main-sequence star. They produce far less energy than larger stars, resulting in low luminosity.
* Low Surface Temperature: Their surface temperatures range from about 2,400 to 3,700 Kelvin, giving them a reddish appearance. This low temperature is a direct result of their lower mass and energy output.
Key Characteristics of Red Dwarfs:
* Small Size: Much smaller than our Sun, often only a fraction of its diameter.
* Long Lifespans: They burn their fuel very slowly, giving them lifespans of trillions of years.
* Common: Red dwarfs are the most numerous type of star in the Milky Way galaxy.
