CNEOS predicts the close approach of the kilometer-sized, Amor class NEO, (164217) 2004 PT42, on 2024-Aug-15 09:10±<00:01 UT at a distance of 0.17961 AU moving with V Relative= 25.91 km/sec, H=17.3 magnitude, diameter 930 m - 2.1 km and 'Rarity'=1. There is a 8946 day observation arc, the Condition Code=0 and the Earth MOID=0.163494 AU. The solution date was 2024-Aug-07 06:20:03 PDT. This MP was discovered at Siding Spring on 2004-08-11 by Siding Spring Survey. This object isn't on MPC's list of PHAs because the MOID is too large. It's predicted to be almost this close again (0.18282 AU) on 2181 Aug 21 15:56 UT.
Using MPC's elements for 2024 Aug 7 0000 UT, ST4.1.11.10 Visual predicts that this MP will have a peak brightness of 14.9 magnitude from the evening of August 14 to the morning of August 16 (the light curve is rather flat due to the distance) when the NEO will be traveling through Aquarius at ~11"/minute. Close approach is predicted (to the nearest hour) on 2024 Aug 15 0500 EDT when the MP will be traveling through Aquarius at ~12"/minute. This large NEO should be brighter than 15.5 magnitude from August 9 (near the Pisces-Pegasus boarder) to August 21 Phoenix.
