Well, that didn’t take long…. the trans-Neptunian object announced on October 27 was precovered in TESS data in this paper posted two days later!!! Han+ in “Seven Years of TESS Precovery Observations of the Dwarf-planet Candidate 2026 ED138” #astrodon #exoplanet

Five images of the object with a combined image showing a clear detection, along with the locations of the planet marked on an orbit from JPL.
