2018 BD is a small asteroid and near-Earth object of the Apollo group , approximately 2–6 meters (7–20 ft ) in diameter. It was first observed on 18 January 2018, by astronomers of the Catalina Sky Survey at Mount Lemmon Observatory , Arizona, United States,[1] just hours before passing about 0.10 lunar distances from the Earth.[2]
Orbit and classification [ edit ]
2018 BD is an Apollo asteroid . It orbits the Sun at a distance of 0.75–1.36 AU once every 13 months (395 days; semi-major axis of 1.05 AU ). Its orbit has an eccentricity of 0.29 and an inclination of 2° with respect to the ecliptic .[2]
The object has an exceptionally low minimum orbital intersection distance with Earth of 900 km; 560 mi (0.000006019 AU ), or 0.002 lunar distances .[2]

Physical characteristics [ edit ]
Based on a generic magnitude-to-diameter conversion, 2018 BD measures between 2 and 6 meters in diameter, for an absolute magnitude of 30.154, and an assumed albedo between 0.05 and 0.20, which represent typical values for carbonaceous and a bright E-type asteroids , respectively.[3] As of 2018, no rotational light curve of this object has been obtained from photometric observations. The body's rotation period , pole and shape remain unknown.[2]
Numbering and naming [ edit ]
This minor planet has neither been numbered nor named .[1]
