2MASS J11193254–1137466 AB (often shortened to 2MASS J1119–1137 AB) is a planetary mass binary located 86±23 light-years from the Earth in the constellation Crater. The components of 2MASS J1119–1137 are each roughly four Jupiter masses. The planetary-mass objects are probably a part of the TW Hydrae association which has an age of approximately 10 million years. The planetary-mass objects are candidate rogue planets.
