It consists of three stars: Rigil Kentaurus (α Centauri A), Toliman (α Centauri B), and(α Centauri C).Proxima Centauri is theto theat 4.2465(1.3020 ). α Centauri A and B arestars ( and , respectively) that togethe. 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.

The closest exoplanets are those found orbiting the star closest to the Solar System, which is Proxima Centauri 4.25 light-years away. The first confirmed exoplanet discovered in the Proxima Centauri system was Proxima Centauri b, in 2016. HD 219134 (21.6 ly) has six exoplanets, the highest number discovered for any star within this range.
Jul 2, 2020· If a third planet in a habitable zone is confirmed, then GJ 887 will likely join the ranks of TRAPPIST-1 as a planetary system of great interest to astronomers and those looking for life beyond Earth.Three Earth-sized rocky planets were identified orbiting TRAPPIST-1 in 2015 and four more terrestrial planets have since been found — making it a prime target for scientists.
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.)

That''s a more manageable number than 25 trillion miles, 40 trillion kilometers or 272,000 AU. Light years also provide some helpful perspective on solar system distances: the Sun is about 8 light minutes from Earth.
The nearest star system, or solar system to ours is called Alpha Centauri. It consists of 3 suns: Alpha Centauri A with Alpha Centauri B forming a binary pair and Proxima Centauri. The system can be viewed year–round in most of the Southern Hemisphere. Betelgeuse is too far away to damage Earth. Credits: All media.
