A newly-discovered asteroid designated 2021 KO2 flew past Earth at a distance of 0.96 LD / 0.00248 AU (371 002 km / 230 530 miles) from the center of our planet on May 30, 2021. This is the 59th known asteroid to fly past Earth within 1 lunar distance since the start of the year and the 8th so far this month.
The object was first observed at Tokyo-Kiso, Japan on May 30, just a few hours before its close approach.
2021 KO2 belongs to the Aten group of asteroids and has an estimated diameter between 6.6 and 15 m (21.6 - 49.2 feet).
The object flew past us at 04:01 UTC at a speed (relative to the Earth) of 15.01 km/s.
The flyby took place less than 24 hours before 2021 KN2, an Apollo-class asteroid also discovered at Tokyo-Kiso.

This is the 60th known asteroid to fly past Earth since the start of the year, the 9th during the month of May, and the third in just 25 hours.
2021 KQ2 was first observed at Tokyo-Kiso, Japan, several hours after it made its close approach to our planet. This is the third <1LD asteroid discovery by Kiso Observatory in ~24 hours.
The object belongs to the Aten group of asteroids and has an estimated diameter between 2.7 and 6.1 m (8.8 to 20 feet).
