Red Dwarf stars that are low in mass can burn continually for up to 10 trillion years!













A Red Dwarf is a small and cool star in a later stage of its life and has a surface temperature of less than 7,200k degrees Fahrenheit.



Red dwarf stars make up the largest population of stars in the galaxy, but they hide in the shadows, too dim to be seen with the naked eye from Earth. Their limited radiance helps to extend their lifetimes, which are far greater than that of the sun.

Scientists think that 20 out of the 30 stars near Earth are red dwarfs. The closest star to the sun, Proxima Centauri, is a red dwarf.

The term "red dwarf" does not refer to a single kind of star. It is frequently applied to the coolest objects, including K and M dwarfs — which are true stars — and brown dwarfs, often referred to as "failed stars" because they do not sustain hydrogen fusion in their cores.

The lower the mass of a red dwarf, the longer the lifespan. It is believed that the lifespan of these stars exceeds the expected 10-billion-year lifespan of our Sun by the third or fourth power of the ratio of the solar mass to their masses; thus, a 0.1 M  red dwarf may continue burning for 10 trillion years.
