Nearest Stars
The closest stars to our solar system, sorted by distance. Most nearby stars are red dwarfs — small, dim stars that are difficult to see with the naked eye despite their proximity.
About Light-Years
A light-year is the distance light travels in one year — about 9.46 trillion kilometers (5.88 trillion miles). It takes light from the nearest star system, Alpha Centauri, over 4 years to reach us. Even with the fastest spacecraft ever launched (Parker Solar Probe at ~700,000 km/h), it would take over 6,000 years to reach the nearest star. The vast majority of our nearest stellar neighbors are red dwarf stars (spectral class M) — small, cool, and too dim to see without a telescope.
