Most red dwarfs are too faint to see without telescopes, making up the majority of nearby stars we cannot observe directly.
This matters because our night sky underestimates the true stellar population around us.
It also emphasizes the need for advanced instruments to study local stellar neighbors.
The closest star to Earth, Proxima Centauri, is a red dwarf that you cannot see without a telescope.
