The star displays an
excess of
near infrared radiation, suggesting it has a
circumstellar disk of dusty debris.[11] This disk has a mean temperature of 75±17 K and is orbiting at an estimated radius of 84±41
AU.[12] A faint stellar companion was detected in 2007 at the
Gemini Observatory, with a separation of 6.09
″±0.03
″ from the primary.[9] This is equivalent to a physical projected separation of 139
AU, which yields an estimated
orbital period of ~1,330 years.[13] The debris disk is orbiting close to the dynamically unstable region of this system.[12]
