Red dwarfs have masses between 0.08 and 0.6 times that of the Sun, but their small size gives them incredible longevity and stability in energy output.
Their small mass challenges traditional star formation models and informs our understanding of stellar physics.
It also increases the chances for orbiting planets to remain in stable habitable zones for billions of years.
Despite being small, red dwarfs quietly dominate the galaxy’s stellar population.
