Close Approach of (363790) 2005 JE46 - PMSchu - 2026-11-04
CNEOS predicts that the kilometer-sized, Apollo-class, NEA, (363790) 2005 JE46 will make a close approach on 2026-Nov-13 19:58±<00:01 UT at a distance of 0.05145 AU moving with V Relative=14.73 km/sec, H=17.9 magnitude, diameter 720 m - 1.6 km and 'Rarity'=2. As of 2026 Aug 25, there was a 15355 day observation arc, the Condition Code=0 and the Earth MOID=0.0289776 AU. The solution date was 2026-Aug-25 07:23:07 PDT. Discovered 2005-05-10 by LINEAR at Socorro. This object is on the MPC's list of Potentially Hazardous Asteroids (PHAs) that you can download using SkyTools.. The observation arc was extended to 1984-06-22. There will be a closer approach on 2097-Nov-11 00:55±<00:01 UT at 0.02586 AU.
Using MPC's orbital elements for the epoch 2026 Sep 25 0000 UT, ST4.1.11.21 Visual Pro predicts that (363790) 2005 JE46 will reach a peak brightness of 13.4 magnitude on the evening of 2026 November 15 with the NEA 0.055 AU distant traveling through Pegasus at ~20"/minute. Close approach is predicted (to the nearest hour) on 2026 Nov 13 at 1600 EST (2100 UT) with the NEA 0.051 AU distant traveling through Pegasus at 13.8 magnitude and 23"/minute, but in daylight as seen from Columbus, Ohio (40°N). I just noticed that I only used a 4 hour difference between UT and EST instead of the correct 5 hours when determining the close approach time. I was still in EDT mode. (363790) 2005 JE46 should be brighter than 16 magnitude from November 7 in Aquila to December 6 in Taurus.
Here's the Object Info dialog for (363790) 2005 JE46:
The orbit for this NEA is well defined so the ephemeris predicted by MPC's orbital elements should yield accurate positions for this object.
Good hunting,
