2016 EU85 is an asteroid, classified as 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.[1][2]

Orbit

2016 EU85 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.[1] It has an Earth minimum orbital intersection distance of 0.0065 AU (972,000 km) which translates into 2.5 lunar distances.[1]

Torino scale

It is currently rated at level 0[4] after being rated at level 1 on the Torino Scale by the NEODyS system.[5] 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 440 metres (1,440 ft; 480 yd).[6] The observation arc was then increased to of 78 days.[7]

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.[8] 2016 EU85 had been observed 14 times[9] at the observatories Mauna Kea (568), Apache Point (705), Pan-STARRS 1 Haleakala (F51) and Magdalena Ridge Observatory (H01).[10]

2016 EU85 was subsequently removed from the list of possible impactors thanks to prediscovery observations found in the Pan-STARRS archive.

Observations

2016 EU85 was observed with the Spacewatch 1.8-meter telescopes and also the Vatican Advanced Technology Telescope.[11][12]
