New 2025 transit timing for HIP 41378 f confirms large TTVs and is combined with prior data on planets d and e in an N-body model to update ephemerides and predict future transits.
Interior structure models show 28 of 34 cold super-puffs are consistent with core accretion while six require non-standard explanations such as impacts or exo-rings.
Decade-long RV data from multiple instruments confirms Pd=278 days for planet d, refines Pe=393 days for e, measures Mf=25 Earth masses confirming low density of 0.166 g cm^-3, and identifies candidate planet h at ~2600 days.
Ten years of observations of the HIP41378 system provide practical lessons for characterizing long-period exoplanets with the upcoming PLATO mission.
