CNEOS predicts that the newly discovered Apollo class NEO, 2025 TP5, will make a close approach on 2025-Oct-15 20:08±00:06 UT at a distance of 0.00065 AU moving with V Relative=8.37 km/sec, H=26.5 magnitude, diameter 13 m - 30 m and 'Rarity'=2. As of Oct 13 there is a 1 day observation arc, the Condition Code=7 and the Earth MOID=0.000603145 AU. The solution date was 2025-Oct-13 23:42:02 PDT. The initial reported observation was by ATLAS-MLO, Mauna Loa on 2025-10-13. Its next close approach is predicted on 2051-Dec-13 09:15 ± 4_12:35 UT at a nominal distance of 0.04 AU. This NEO is too small to make the MPC's list of Potentially Hazardous Asteroids (PHAs) that you can download using SkyTools.
Using MPC's orbital elements for the epoch 2025 Oct 14 0000 UT, ST4.1.11.18 Visual Pro predicts that 2025 TP5 will reach a peak brightness of 12.6 magnitude on 2025 Oct 15 at 1500 EDT (1900 UT) with the NEO 110.3k km distant traveling through Andromeda at 14.1"/second, but in daylight in Columbus, Ohio. Close approach is predicted (to the nearest hour) on 2025 Oct 15 at 1600 EDT (2000 UT) with 2025 TP5 103.5k km distant traveling through Cassiopeia at 16.6"/second and 12.7 magnitude in daylight in Columbus. This NEO is predicted to be brighter than 16 magnitude on the morning of October 15 in Aquarius and in the evening of October 15 in Ursa Major.
Here's the Object Info dialog for 2025 TP5:
Since this NEO will pass very close by, observers should follow the instructions in the 'Important Thread' at the top of this forum section to download the most up-to-date orbital elements for the best accuracy.
Good hunting,
