2018 VG18
While it is clear that the current heliocentric distance of this object
is between 125 and 130 AU, the exact nature of the orbit is unclear. The
orbit below is the lowest r.m.s. solution from the range of orbits
investigated. The ephemeris uncertainty remains less than 10" for several
months.
