Information
has glosseng: TVLM513-46546 is an ultracool red dwarf in the constellation Boötes, exhibiting a flare star activity and all the same varying semi-regularly due to dissimilarly bright hemispheres and a rotation period of about two days. The star has a mass as low as 90 times the mass of Jupiter (or 9 percent of Sun's mass) and an estimated radius of 11 percent that of Sun (nearly a Jupiter-sized star). The star also shows hints of an unseen companion with undetermined mass. Future monitoring will be able to confirm or rule out low-mass stellar or even planetary mass companions (down to 2-10 Jupiter masses), with orbital periods spanning between 1 and 15 days. . Assuming a stellar luminosity of 0.042 percent that of Sun, the habitable zone where an Earth-like planet may retain liquid water at comfortable temperatures would be located within 0.02 Astronomical Units (roughly 10 times the distance of the Moon from Earth).

Es una estrella muy tenue de magnitud aparente +11,0, una enana roja de tipo espectral M8.5 en el extremo inferior del límite de masa para las estrellas. Con una temperatura superficial en torno a 2200 K, su masa es de 0,09 masas solares, por lo que efectivamente es una estrella de muy baja masa y no una enana marrón.
