This likely makes its point of origin the nearby Scorpio–Centaurus Complex.〔 It is a BY Draconis variable showing a rotational modulation with a period of 1.75 days, and has been observed to flare.〔
An infrared excess has been detected around this star, most likely indicating
the presence of a circumstellar disk at a radius of 17.9 AU. The temperature of this dust is 52 K.〔
