J Centauri (J Cen) is a star in the constellation Centaurus. It is approximately 350 light years from Earth. J Centauri is a spectral class B3V main sequence star with a mean apparent magnitude of 4.5 and a luminosity 500 times that of the Sun. The temperature of the star's photosphere is nearly 24,000 K. The rotation velocity at the equator is at least 223 km/s. It is believed to be a binary star system. This star may be a member of the Scorpio-Centaurus OB association (Sco OB2). This is one of the nearest regions of recent star formation.

(en) HD 116087 ( eller HR 5035) är en antagen dubbelstjärna i den södra delen av stjärnbilden Kentauren som också har Bayer-beteckningen J Centauri. Den har en kombinerad skenbar magnitud av ca 4,51 och är svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 9,2 mas, beräknas den befinna sig på ett avstånd på ca 350 ljusår (ca 109 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 6 km/s och kan ingå i OB-föreningen Scorpius-Centaurus. Den är en av de närmaste nyligen bildade stjärnorna.

S'hi aproximadament a 350 anys llum de la Terra. J del Centaure és una estrella de la seqüència principal de tipus espectral B3V amb una magnitud aparent mitjana de 4,5 i una lluminositat 500 vegades la del Sol. La temperatura de la fotosfera de l'estrella és de prop de 24.000 K. La velocitat de rotació a l'equador és d'almenys 223 km/s. Hom creu que és un sistema estel·lar binari. (ca) HD 116087 (J Centauri) é uma estrela binária na constelação de Centaurus. Com uma magnitude aparente visual de 4,51, é visível a olho nu em locais sem excesso de poluição luminosa. De acordo com medições de paralaxe pelo satélite Gaia, está localizada a aproximadamente 367 anos-luz (113 parsecs) da Terra. A essa distância, sua magnitude é diminuída em 0,07 devido à extinção causada por gás e poeira no meio interestelar. O sistema é membro do subgrupo Centaurus Inferior-Crux da , a associação OB mais próxima do Sol. (pt)
