SMC 018136 (original) (raw)
SMC 018136, also known as PMMR 37, is a red supergiant star located in the Small Magellanic Cloud. It is one of the largest stars and one of most luminous SMC cool supergiants so far discovered, with a radius of 1,310 times that of the sun and a bolometric luminosity over 200,000 times more than Sun. If it were in the place of the Sun, its photosphere would at least engulf the orbit of Jupiter. SMC 018136 has a spectral type M0 Ia and an effective temperature 3,575 K, although more recent papers suggest it has a slightly earlier spectral type of K4.5 Ia-Ib.

| dbo:abstract | SMC 18136 est une lointaine supergéante rouge située dans le Petit Nuage de Magellan. Cette étoile, qui a été découverte par l'astronome Roberta M. Humphreys en 1979, est connue pour être l'une des plus grandes étoiles à avoir été observée. Une récente estimation de sa taille a permis d'observer que l'étoile a rayon de 1310 R☉ et que, si elle remplaçait le Soleil au centre du système solaire, sa photosphère s'étendrait jusqu'à une distance de 6,09 UA, près de l'orbite de la planète Saturne. Une récente mesure (2020) de son mouvement par le Radial Velocity Experiment a permis d'estimer sa distance par rapport à la Terre à 8 142 ± 2 434 pc (∼26 600 a.l.). Cependant, une mesure annuelle de sa parallaxe par le satellite Gaia donne une distance d'environ 49 750 pc (∼162 000 a.l.), ce qui est plus cohérent avec son appartenance au Petit Nuage de Magellan.
