is a near-Earth asteroid of the Aten group, approximately in diameter. On 3 June 2014 around 17:38 UT (± 3 hours), it is crudely estimated to have passed about from Earth. The asteroid was discovered on 2 June 2014 by the Mount Lemmon Survey at an apparent magnitude of 21 using a reflecting telescope.

Uncertainty With an observation arc of about 1 hour, the trajectory is poorly constrained and the asteroid has an uncertainty parameter of 9 making long-term predictions of the asteroids position nearly impossible. The nominal (best fit) orbit shows that passed from Earth on 3 June 2014 (~12,700 km from Earth's surface). But the uncertainty region shows that the asteroid could have approached Earth as close as or as far as . Since Earth has a radius of approximately 6,400 km, the asteroid did not come any closer than about 2,600 km from Earth's surface.

Moon The nominal orbit shows that passed from the Moon on 4 June 2014. But the uncertainty region shows that the asteroid could have impacted the Moon or passed as far as . But it is very unlikely that the asteroid impacted the Moon.
