Planed allheulol yw Proxima Centauri b (gelwir hefyd yn Proxima b[1][2]) sy'n cylchdroi o fewn parth trigiadwy'r seren corrach coch Proxima Centauri, y seren agosaf i'r Haul. Mae wedi ei leoli tua 4.25 blwyddyn golau (1.3 parsec, neu 40,140,000,000,000 km) i ffwrdd o'r Ddaear yng nghytser Centaurus. Hwn yw'r blaned allheulol agosaf i Gysawd yr Haul, yn ogystal â'r allblaned agosaf rydym yn gwybod amdano a allai gynnal bywyd.

Darganfuwyd y blaned gan dîm wedi ei arwain gan Guillem Anglada-Escudé o Queen Mary, Prifysgol Llundain a cyhoeddwyd y darganfyddiad yng nghylchgrawn Nature ar 24 Awst 2016.[3][4][5]
