Known Distance Objects dates of past/future Perihelion/Aphelion

I'm interested in viewing the approximate Time of perihelion of the various known distance objects. This could even be extended to include past/future Perihelion/Aphelion. For some objects it may be completely unknown, or a work in progress, as in FarFarOut whose Wikipedia page says "Time of perihelion ≈ 1758?" but others may already be part of models that currently predict these dates, such as Eris whose Wikipedia page explains, "Using numerical integration JPL Horizons shows Eris came to perihelion around 1699, to aphelion around 1977, and returning to perihelion around December 2257."

Orbital Period might be another column of interest for the table.

2017 DP121

For 2017 DP121, its distance is marked to be greater than its aphelion. That should not be possible, I think?Am I wrong? 109.240.131.161 (talk) 13:46, 14 September 2021 (UTC)[reply]

The orbital values for 2017DP121 were wrong. With a condition code of 8, aphelion (Q) is 94 ± 17au. With a 1 year observation arc, the orbit is not well constrained. Thank you for pointing that out. -- Kheider (talk) 14:32, 14 September 2021 (UTC)[reply]
