Шаблон:Mp is a small asteroid and near-Earth object of the Apollo group, approximately Шаблон:Convert 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
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 Шаблон:Convert, or 0.002 lunar distances.[2]

Physical characteristics
Based on a generic magnitude-to-diameter conversion, Шаблон:Mp 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
This minor planet has neither been numbered nor named.[1]
