Английская Википедия:2018 PD20
Шаблон:Mp is a small asteroid, classified as a near-Earth object of the Apollo group, approximately Шаблон:Convert in diameter. On 11 August 2018, it was first observed by ATLAS at the Mauna Loa Observatory on Hawaii Шаблон:Obscode,[1] when it passed Шаблон:Convert from the Earth.[2] 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 Шаблон:Convert, approximately 3 times the width of the Earth.
Orbit and classification
Шаблон:Mp 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.[2]
The asteroid has an Earth minimum orbital intersection distance of Шаблон:Convert, which translates into 0.078 lunar distances.[2]
