CNEOS predicts that the newly-discovered, small, Apollo-class NEA, 2026 TG9, will make a close approach on 2026-Oct-14 04:57±00:21 UT at a distance of 0.00152 AU moving with V Relative=11.63 km/sec, H=27.0 magnitude, diameter 10 m - 23 m and 'Rarity'=1. As of October 10, there is a 1 day observation arc, the Condition Code=8 and the Earth MOID=0.000777625 AU. The solution date was 2026-Oct-10 12:12:02 PDT. The initial reported observation was by University of Arizona Mt. Lemmon Survey on 2026-10-09. This object is too small to make the MPC's list of Potentially Hazardous Asteroids (PHAs).
Using MPC's orbital elements for the epoch 2026 Oct 11 0000 UT, ST4.1.11.21 Visual Pro predicts that 2026 TG9 will reach a peak brightness of 14.6 magnitude on October 13 2200 EDT (October 14 0200 UT) with the NEA traveling through Triangulum at ~480"/minute at 263k km distant. Close approach is predicted (to the nearest hour) on 2026 October 14@0100 EDT (0500 UT) with the NEA traveling through Perseus at 15.1 magnitude and 10.4"/second and 230.6k km distant. The NEA passes close to Algol on October 13 ~2320 EDT as seen from Columbus, Ohio.

Here's the predicted path for 2026 TG9:
The observation arc for this object is only 1 day, so the orbit is still uncertain. Observers should follow the instructions in the "Important Threads" section of this forum section for instructions for downloading orbital elements from JPL's HORIZONS system near their time of observation.
Good hunting,
