Dwarf Stars and Giant Stars

What is a red dwarf?

A red dwarf is another name for a low-mass, main-sequence star. They are cool compared to most other kinds of stars (their photospheric temperature is about 6,000 degrees Fahrenheit, or 3,000 degrees Kelvin), so they glow a dull red. Red dwarfs are small and faint compared to most other kinds of stars.
