under observation for a sufficient length of time to determine accurate orbital elements, it is estimated to be orbiting at an average separation of at least 24.9 AU with an orbital eccentricity of 0.16 or more and orbital period of a minimum of 124 years. This companion may be a red dwarf star, which would explain the observed X-ray flux from this system. References External links Boyajian, Tabetha S. et al., 2012. Stellar Diameters and Temperatures.
