Es un sistema formado por tres estrellas unidas gravitacionalmente. Un sistema ternario de estrellas que orbitan un centro de masas, Alfa Centauri A y Alfa Centauri B, más una tercera estrella enana roja, Alfa Centauri C (Próxima Centauri), que orbita alrededor de las dos estrellas Alfa Centauri A y B.

10 de feb. de 2022 · Proxima Centauri, also known as Alpha Centauri C, is the nearest star to Earth and the Sun. It is a red dwarf with three confirmed planets, one of which may be habitable, and a variable star that flares and produces X-rays.
Próxima Centauri o Alfa Centauri C nb 1 (del latín proximus, -a, -um: «siguiente a» o «cercana a») 9 es una estrella enana roja de 11.ª magnitud aparente situada a aproximadamente 4,22 años luz (1,295 pársecs) nb 2 de la Tierra, en la constelación de Centaurus y posiblemente perteneciente al sistema de Alfa Centauri.
Proxima Centauri c (also called Proxima c or Alpha Centauri Cc) is a controversial exoplanet candidate claimed to be orbiting the red dwarf star Proxima Centauri, which is the closest star to the Sun and part of a triple star system.
Alpha Centauri C, better known as Proxima Centauri, is a small main-sequence red dwarf of spectral class M6-Ve. It has an absolute magnitude of +15.60, over 20,000 times fainter than the Sun. Its mass is calculated to be 0.1221 M ☉. It is the closest star to the Sun but is too faint to be visible to the naked eye.
31 de oct. de 2013 · Proxima Centauri is the star closest to our Sun, but not visible to the naked eye. It is part of a triple star system with Alpha Centauri A and B, which lie out of frame in this Hubble image.
30 de nov. de 2021 · Proxima Centauri is the dimmest and smallest of the Alpha Centauri system, but it has the honor of being the nearest star to the Sun. Learn about its physical characteristics, exoplanets, flares, and mythology in this article.
