Proxima Centauri^[9] inggih punika bintang alit mamassa éndép sané magenah 4.2465 warsa cahaya (1.3020 pc) dohné saking Surya ring rasi bintang kelod saking Centaurus. Aran Latiné maartos '[bintang] pinih nampek saking Centaurus'. Ipun kacunduk duk warsa 1915 olih Robert Innes saha pinaka bintang pinih nampek sané kauningin sareng Surya. Antuk magnitudo semu mendem agengné 11,13, ipun bes redup antuk kacingak nganggén panyingakan malalung. Proxima Centauri inggih punika anggota Alpha Centauri sistem bintang, sané kaidentifikasi dados komponén Alpha Centauri C, lan magenah 2,18° kelod kauh pasangan Alpha Centauri AB. Sané mangkin magenah 12,950 AU (0.2 ly) saking AB, sané mangorbitné sareng period sawatara 550.000 warsa.
