Asteroid 2020 JJ flew past Earth at just 0.03 LD on May 4 -- the closest of the year and 6th closest on record

Asteroid 2020 JJ flew past Earth at just 0.03 LD on May 4 -- the closest of the year and 6th closest on record

A newly-discovered asteroid designated 2020 JJ flew past Earth at a very close distance of 0.03 LD / 0.0000896 AU (13 403 km / 8 328 miles) at 12:05 UTC on May 4, 2020.

This is the 40th known asteroid to flyby Earth since the start of the year and the second of the month. This is also the closest asteroid flyby since October 31, 2019 (2019 UN13), and the 6th closest asteroid flyby on record.

2020 JJ belongs to the Apollo group of asteroids. It was first observed at Mt. Lemmon Survey, Arizona just a couple of hours before its close approach.

The object has an estimated diameter between 2.7 and 6 m (8.8 to 19.7 feet).
