“However, it is not listed as a Potentially hazardous asteroid due to its small size.”
I’d like to change this to:
“It is not listed as a potentially hazardous asteroid given its size (7 feet in diameter) is smaller than the threshold for potentially hazardous objects (460 feet in diameter).” And then cite the 460 foot threshold source. Any objections? - Scarpy (talk) 06:49, 23 August 2020 (UTC)Reply
Strangely, the JPL Horizons solution gives minimum distance 0.0028 AU, or 419,000 km, beyond the moon!? Tom Ruen (talk) 19:57, 25 August 2020 (UTC)Reply

The OR/WA fireball seen at 3 November 2020 03:11 UT was ~26 hours too late to have anything to do with a 2 November 2020 01:12 UT virtual impactor. In 26 hours Earth will move 2.8 million km from the orbit crossing. The impact window is only roughly 8 minutes wide. -- Kheider (talk) 19:17, 3 November 2020 (UTC)Reply
