P/2025 D3 (PANSTARRS) - see also this minor planet center link and jpl horizons link.
Currently in the Hilda region, according to a backward Mercury6 simulation done using the current orbital parameters, it might have entered the solar system 200K years ago (high uncertainty, yet comet origin very likely).
Orbit "unstable" and very much influenced by Jupiter (last close encounter occurred on Dec 23rd, 2021).
