2018 CF2 belongs to the Apollo group of asteroids and has an estimated diameter of 6.6 - 15 m (21.6 - 49.2 feet). It was first observed at Mt. Lemon Survey on February 7, 2018, and it flew past us at a speed (relative to the Earth) of 13.54 km/s at 19:16 UTC on February 6.
This is the 10th of 13 known asteroids to flyby Earth within 1 lunar distance since the start of the year. It was also the first of two such asteroids on February 6, just 57 minutes before 2018 CC.
