Red Dwarfs – The Quiet Fires of the Universe
A red dwarf is a small, relatively cool star that shines with a dim red light. In terms of size, it’s only about 7% to 50% the mass of our Sun. That means if our Sun were a basketball, a red dwarf might be the size of a golf ball.
Their “red” color comes from their cool surface temperatures — usually around 2,000 to 4,000°C.
