A newly discovered asteroid 2016 VB1 will flyby Earth at 0.68 LD (261 120 km / 162 252 miles) from the surface on November 7, 2016. The closest approach is expected at 15:56 UTC.

This is a rare, Atira class asteroid first observed by Mt. Lemmon Survey on November 5, 2016. Its estimated size is 3 – 12 m (10 – 40 feet). 2016 VB1 will flyby Earth at a relative velocity of 5.72 km/s.

Atira is a class of near-Earth asteroids whose orbits are contained entirely with the orbit of the Earth and are therefore alternatively called Interior-Earth Objects (IEO).

Until recently, there were only 6 known asteroids of this type.
