, provisional designation, is a sub-kilometer asteroid and near-Earth object of the Apollo group, approximately 280abbr=offNaNabbr=off in diameter. After its discovery by the Catalina Sky Survey at the Catalina Station in Arizona, United States, this potentially hazardous asteroid was briefly listed at a Torino Scale of 1 and a cumulative Palermo Scale of −0.87. It was removed from the Sentry Risk Table on 26 June 2013.

Numbering and naming

This minor planet was numbered by the Minor Planet Center on 18 May 2019 . As of 2019, it has not been named.

Orbit and classification

orbits the Sun at a distance of 0.98–1.38 AU once every 15 months (468 days; semi-major axis of 1.18 AU). Its orbit has an eccentricity of 0.17 and an inclination of 26° with respect to the ecliptic.

Even though has an Earth MOID of 9E-05abbr=onNaNabbr=on, the orbit and future close approaches are well determined with an orbital uncertainty of 1.

On 23 November 2059, will pass 0.0046abbr=onNaNabbr=on from Earth. On 23 November 2199, it will make another close approach at a distance of 0.0005abbr=onNaNabbr=on to 0.069 AU, but since it is a close approach and the exact distance in uncertain, future close approaches after 2199 are uncertain.

2014 passage

The 21 May 2014 Earth close approach of 0.3622abbr=onNaNabbr=on should allow a refinement to the orbit. From 7 May 2014 until 2 June 2014 the asteroid will be brighter than apparent magnitude 20. The asteroid will come to opposition on 18 May 2014 when it will be up all night.
