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.
