2013 RF98 is a Trans-Neptunian object.[1] 2013 RF98 is part of the evidence for the Planet Nine hypothesis because it shares a similar Argument of perihelion with other potentially shepherded TNOs.
It came to perihelion (closest approach to the Sun) in November 2009 and was last observed in September 2016.[2] As of October 2016, it is 36.6 AU from the Sun. Of the seven objects whose aligned orbits suggest the existence of Planet Nine, it is currently the closest to the Sun. It will be 18.7 AU from Uranus in 2021. It will be in the constellation of Cetus until 2022. It comes to opposition at the start of November.
