A newly discovered, very small asteroid designated 2017 UL6 will flyby Earth at 0.16 LD or 0.00040 AU (~ 59 839 km / 37 182 miles) at 11:24 UTC on October 28, 2017. This is the 45th known asteroid to flyby Earth within 1 lunar distance since the start of the year and the 6th closest.
2017 UL6 belongs to the Apollo group of asteroids and was first observed at Mt. Lemmon Survey on October 27, one day before its close approach.
This asteroid has an estimated diameter between 1 and 2.3 m (3 - 7 feet). It will fly past our planet at 11:24 UTC on October 28 at a speed (relative to the Earth) of 8.03 km/s.
This is the 9th known asteroid to flyby Earth within 1 lunar distance this month, 45th since the start of the year and the 6th closest. It is also one of the smallest this year (within 1 LD).
