The discovery of 2023 KQ14 (and 2013 FT28) are completely consistent with the updated maximum likelihood orbit of the Planet Nine of Brown and Batygin, (2024) and incompatible with the Planet X of (Siraj et al., 2025). Find out why at: www.cloudynights.com/topic/686170....

Is it possible any of these objects could be Mars, or Mercury sized? Would such a mass be allowed...

Very recent papers by Pichierri and Batygin (drive.google.com/file/d/1zLvX...) and Siraj, et al.(drive.google.com/file/d/1k8qF...) should have pulled 2023 KQ14 out of the JPL database, but didn't.

This is from the 2019 Planet Nine Hypothesis figure 10.

The Planet Nine hypothesis does predict these objects in this range of semi-major axes. I'm curious why we haven't seen a peer reviewed paper on it yet.

This object bears a resemblance to 2013 FT28 in that it is similarly aligned in longitude of perihelion with the hypothetical Planet Nine. It's semi-major axis quite similar, but it's large perihelion means it's probably quite stable, whereas 2013 FT28 is metastable.
