According to the JPL Small-Body Database Browser period of this object is more than 612,000 years and the aphelion (Q) is more than 14,411 A.U. That is almost a quarter of a light-year.
This is based on the latest observation in 2018 and there is no computation of uncertainty, so the specifics are likely to change. But clearly this thing is coming from way out there. |
