will come to perihelion around 2198, at a distance of about 36 AU.〔 It is currently near aphelion, 80 AU from the Sun, and, as a result, it has an apparent magnitude of 22.〔 Its orbit has a significant inclination of 33°.〔
First observed on 17 March 2013, it has an observation arc of about one year.〔 It came to opposition in early March 2014.
