https://kosmonauta.net/2020/10/dziesiec-bliskich-przelotow/10 newly-discovered asteroids within 1 lunar distance in 10 daysPosted by Teo Blašković on October 18, 2020 at 11:27 UTC
10 newly-discovered asteroids with a close approach within 1 lunar distance (<1LD asteroid) were discovered from October 12 to 18, 2020, marking a significant increase in detection and flybys of asteroids within 1 lunar distance in such a short period of time.
9 newly-discovered asteroid flybys were detected from October 15 to 18.
Over the next 3 days (October 18 - 21), 5 newly-discovered asteroids will fly past Earth within 1 lunar distance.
From October 1 to 18, our sky surveys have detected 12 <1LD asteroids, tying the month with September 12 days before the end of the month.
There are now 84 known asteroids to flyby Earth within 1 lunar distance since the start of the year, including 2020 SO on December 1.
2020 now has now surpassed 2019 by 7 <1LD asteroids and holds the record for the closest asteroid flyby.
This report summarizes 10 newly-discovered <1LD asteroid flybys from October 12 to 21 in chronological order, with links to CNEOS' and Minor Planet Center's detailed pages for each object.
Detailed statistics for the current month and the year are at the end of the report.
