2MASS J2126–8140
2MASS J21265040−8140293, also known as 2MASS J2126−8140, is an exoplanet orbiting the red dwarf TYC 9486-927-1, 111.4±0.3 light-years away from Earth. It has both the longest (~900 thousand years) and the widest orbit (>4500 AU) of any known planetary mass object. Its estimated mass, age (10-45 million years), spectral type (L3), and Teff (1800 K) are similar to the well-studied planet β Pictoris b.
