2M1510 (full designation: 2MASS J15104761–2818234) is a triple or possibly quadruple system of gravitationally bound brown dwarfs, consisting of the eclipsing binary 2M1510AB and the wide companion 2M1510C. 2M1510AB was found to be an eclipsing binary in the first light data of the SPECULOOS telescopes. It is only the second eclipsing binary brown dwarf found so far (as of March 2020), the other is 2M0535-05. The system verified theoretical models for how brown dwarfs cool. The system is located 120 light-years away from Earth in the constellation Libra.
