Close Approach of 2025 TC - PMSchu - 2025-10-02 CNEOS predicts that the newly discovered Apollo class NEO, 2025 TC, will make a close approach on 2025-Oct-03 06:34±<00:01 UT at a distance of 0.00057 AU moving with V Relative=16.15 km/sec, H=27.0 magnitude, diameter 11 m - 24 m and 'Rarity'=2. There is a 2 day observation arc, the Condition Code=7 and the Earth MOID=0.000370874 AU. The solution date was 2025-Oct-02 06:59:42 PDT The initial reported observation was by Pan-STARRS 1, Haleakala on 2025-10-01. The observation arc was extended by 2 observations on 2025-09-30 and 3 observations on 2025-10-01 by Palomar Mountain--ZTF. This object is too small to make the MPC's list of Potentially Hazardous Asteroids (PHAs) that you can download using SkyTools. This NEO is predicted to pass 0.86 AU from Jupiter on 2054-Oct-13 13:53 ± 1_01:07 UT. Using MPC's orbital elements for the epoch 2025 Oct 2 0000 UT, ST4.1.11.18 Visual Pro predicts that 2025 TC will reach a peak brightness of 13.6 magnitude on 2025 Oct 3 at 0100 EDT (0500 UT) at a distance of 126.1k km traveling through Grus at 19"/second on the horizon in Columbus, Ohio. Close approach is predicted (to the nearest hour) on 2025 Oct 3 at 0300 EDT (0700 UT) at a distance of 90.17k km traveling through Cirinus at 32"/second and 15.2 magnitude, but below the horizon in Columbus. This is one of the fastest apparent motions that I've seen for a close approach so it should be very impressive to observe. It should be brighter than 15 magnitude in Aquarius on the evening of Oct 2. Best views will be from the southern hemisphere. Here's the Object Info dialog for 2025 TC: Since this NEO will pass very close, observers should follow the instructions in the 'Important Thread' at the top of this forum section to download the most accurate orbital elements.
