The binary has a maximum separation of 1 arcsec with less than 0.1 mags difference between components with identical ultra-red colors (g-i=1.49+-0.01 mags). The orbit of the mutual components was found to have a period of 961.2+-4.6 days with a semi-major axis of 21000+-160 km and eccentricity of 0.1529+-0.0028. The inclination is 15.68+-0.22 degs and the mirror orbit rejected at high confidence. The total system mass is 7.90+-0.21 x 10^17 kg.
