SDSS J024749.90−163112.6 is a spectroscopic candidate for a double system of two T dwarfs in the constellation Eridanus (as of 2012).
The object was initially identified through analysis of data from the Sloan Digital Sky Survey (SDSS) by Chiu et al. identified as a T2 dwarf. A spectroscopic study by Burgasser et al. gave clear indications that it could be a double system, the components of which belong approximately to the spectral classes T0 and T7.
