is an asteroid, classified as a near-Earth object and potentially hazardous asteroid of the Apollo group, approximately 400 meters in diameter. It was first observed on 10 March 2016, by the Pan-STARRS survey at Haleakala Observatory, Hawaii, United States.
Orbit
orbits the Sun at a distance of 1.0–2.7 AU once every 2 years and 6 months (918 days). Its orbit has an eccentricity of 0.48 and an inclination of 3° with respect to the ecliptic. It has an Earth minimum orbital intersection distance of which translates into 2.5 lunar distances.
Torino scale
is currently rated at level 0 after being rated at level 1 on the Torino Scale by the NEODyS system. It was upgraded to level 1 on 25 March 2016 but downgraded on 30 March 2016. On the Sentry system it did not cross the threshold between the two levels, due to a lower computed impact probability. The asteroid is estimated to have a diameter of . The observation arc was then increased to 78 days.
When rated at Torino Scale level 1, there was a 0.0012% chance or a 1 in 83,000 chance of the asteroid colliding with the Earth, corresponding to a 99.9988% chance the asteroid will miss the Earth. had been observed 14 times at the observatories Mauna Kea (), Apache Point (), Pan-STARRS 1 Haleakala () and Magdalena Ridge Observatory ().
was subsequently removed from the list of possible impactors thanks to prediscovery observations found in the Pan-STARRS archive.
Observations was observed with the Spacewatch 1.8-meter telescopes and also the Vatican Advanced Technology Telescope.
