Asteroid 2018 GE3 flew past Earth at 0.5 LD
A newly discovered asteroid designated 2018 GE3 flew past Earth at a very close distance of 0.5 LD or 0.00129 AU (~192 981 km / 119 912 miles) on April 15, 2018. This is the 28th known asteroid to flyby Earth within 1 lunar distance since the start of the year and the second largest.
This object belongs to the Apollo group of asteroids. It was first observed at Catalina Sky Survey on April 14, just hours before its closest approach.
Asteroid 2018 GE3 has an estimated diameter between 48 and 110 m (157 and 360 feet) and it flew past February 15, 2013 Earth at a speed (relative to the Earth) of 29.58 km/s.
This is the 3rd known asteroid to flyby Earth within 1 lunar distance this month and the 28th since January 1. It is also the second largest known object to flyby Earth within 1 LD since the start of the year.
For comparison, an asteroid that exploded some 29.7 km (18.5 miles) above the Russian city of Chelyabinsk on damaging over 3 000 buildings and injuring over 1 500 people (mostly by broken window glass), had an estimated size of approximately 20 m (65 feet). Its light was brighter than the Sun, visible up to 100 km (62 miles) away.
Chelyabinsk asteroid, officially named Chelyabinsk meteorite, was undetected before its atmospheric entry, in part because its radiant was close to the Sun.
In the hours following the visual meteor sighting, a 6-meter (20 feet) wide hole was discovered on Lake Chebarkul's frozen surface and scientists from the Ural Federal University collected 53 samples from around the hole the same day it was discovered.
