A newly discovered asteroid designated 2018 YL2 flew past Earth at a very close distance of 0.15 LD / 0.00040 AU (59 839 km / 37 182 miles) on December 27, 2018.
This object belongs to the Apollo group of asteroids. It was first observed at ATLAS-MLO, Mauna Loa, Hawaii on December 28, one day after its close approach to our planet.
2018 YL2 has an estimated diameter between 3.6 and 8.1 m (11.8 and 26.6 feet). It flew past us at a speed (relative to the Earth) of 11.34 km/s at 17:33 UTC.
This is the third asteroid to flyby Earth within 1 lunar distance this month and the 74th since the start of the year.
