216433 Milianleo, provisional designation Шаблон:Mp, is an Aeolia asteroid from the central region of the asteroid belt, approximately Шаблон:Convert in diameter. It was discovered 19 February 2009, by German amateur astronomer Erwin Schwab using a remote-controlled telescope at Tzec Maun Observatory Шаблон:Obscode in Mayhill, New Mexico, United States. The asteroid was named after the discoverer's son, Milian Leo Schwab.[1]
Orbit and classification
Milianleo is an attributed member of the small Aeolia family (Шаблон:Small),[2][3] a small asteroid family of less than 300 known members, named after its parent body and largest member, 396 Aeolia.[4] It orbits the Sun in the central main-belt at a distance of 2.4–3.1 AU once every 4 years and 6 months (1,658 days; semi-major axis of 2.74 AU). Its orbit has an eccentricity of 0.13 and an inclination of 3° with respect to the ecliptic.[5] It was first observed as Шаблон:Mp at Lincoln Laboratory ETS in 2000, extending the body's observation arc by 9 years prior to its official discovery at Tzec Maun.[1]
On 25 December 2098, Milianleo is expected to pass 4,449,642 kilometers from the asteroid 704 Interamnia.[5] It will pass it at a relative velocity of 7.12 kilometers per second.
Physical characteristics
Milianleo is likely an X-type asteroid, based on its membership to the Aeolia family.[4]Шаблон:Rp When using a generic magnitude-to-diameter conversion, this asteroid measures approximately 1.6 kilometers in diameter, for an absolute magnitude of 16.5,[1][5] and an assumed visual geometric albedo of 0.17, taken from the Aeolia family's parent body.[6][4]Шаблон:Rp As of 2018, no rotational lightcurve of Milianleo has been obtained from photometric observations. The body's rotation period, pole and shape remain unknown.[5][2]
Naming
This minor planet was named after Milian Leo Schwab, the first-born son of German amateur astronomer and discoverer Erwin Schwab.[1][7] The approved naming citation was published by the Minor Planet Center 4 October 2009 (Шаблон:Small).[8]
