 As typical for long-period planets discovered around other stars, it has an orbital eccentricity greater than that of Jupiter.The discoverers estimate its effective temperature as 264 K from solar heating, but it could be at least 10-20 K warmer because of internal heating.Preliminary astrometric measurements suggested that the orbital inclination is 170.3°, yielding an object mass of 38 times that of Jupiter, which would make it a brown dwarf.
