The closest star system and closest planetary system to Earth's Solar System is Alpha Centauri, which is 4.37 light-years (1.34 parsecs) away from the Sun12. In orbit around Alpha Centauri is Proxima Centauri, which is too faint to be visible to the unaided eye. At a distance of 4.25 light years, Proxima is the closest-known star to our solar system2.

Overview Most of the exoplanets discovered so far are in a relatively small region of our galaxy, the Milky Way. ("Small" meaning within thousands of light-years of our solar system; one light-year equals 5.88 trillion miles, or 9.46 trillion kilometers.) Even the closest known exoplanet to Earth, Proxima Centauri b, is still about 4 light-years []
