2MASS J12373919+6526148 (hereafter 2MASS 1237+6526) is a brown dwarf object with late spectral type T in the constellation of Draco, nearly 34 light-years away from the Sun.

[3] The substellar object could likely host a very low-mass companion (yet undetected but inferred), possibly in the planetary regime.

[5] Burgasser et al. (2003)[2] have inferred the presence of a low-mass companion orbiting the brown dwarf 2MASS 1237+6526.

Such object would yield a mass between 3 and 12 times that of Jupiter and take nearly 4.56 hours (0.19 days) to revolve around its dim primary.

Accounting very faint luminosity of the primary (6.25/1,000,000th of Sun's luminosity), the habitable zone is located within 0.0025 astronomical units, so the putative planet could likely retain great amounts of water and ammonia.
