is a small asteroid, classified as a near-Earth object of the Apollo group, approximately in diameter. On 11 August 2018, it was first observed by ATLAS at the Mauna Loa Observatory on Hawaii , when it passed from the Earth. This is notable because it came within a tenth of the lunar distance, or 0.10 LD which is closer to Earth than satellites in a geostationary orbit. These have an altitude of 0.11 LD, about , approximately 3 times the width of the Earth.

Orbit and classification

orbits the Sun at a distance of 0.82–1.66 AU once every 17 months (503 days; semi-major axis of 1.24 AU). Its orbit has an eccentricity of 0.34 and an inclination of 9° with respect to the ecliptic.

The asteroid has an Earth minimum orbital intersection distance of , which translates into 0.078 lunar distances.
