Thanks, it helps quite a bit to be able to visualize what they're talking about.
Out at 90 AU, and by the year 3000 is out at 500 AU, and that's still not anywhere near maximum distance. Looked like it was going to be 10,000+ years orbits or longer, and probably out at several 1000 AU at maximum.
Little skeptical it would even orbit normally with how heavily eccentric it is, and the extreme distance at maximum. Way... out beyond the heliopause / heliosheath / termination shock.
Does anyone know if this has its PE in alignment with the other Sedna type objects found?
I think there is a tendency for them to have their PE out to one side and the AP out to the other giving a fairly obvious pattern indicating another larger object is shepherding the others into their orbits.

The fun part is the ~1700 AU aphelion is still not far enough out to be part of the Oort cloud. https://science.nasa.gov/solar-system/oort-cloud/facts/
Well, the preprint announcing the discovery describes its orbit as extending to "the inner Oort cloud" even though aphelion is 1630 au.

The preprint announcing the discovery lists the semi-major axis as 838 au, so the major axis is 1676 au and aphelion is about 1630 au.
