216433 Milianleo, provisional designation 2009 DM3, is an asteroid from the middle region of the asteroid belt, approximately 2 kilometers in diameter. It was discovered 19 February 2009, by German amateur astronomer Erwin Schwab using a remote-controlled telescope at Tzec Maun Observatory in New Mexico, United States. The asteroid was named after the discoverer's son, Milian Leo Schwab.[2]
Orbit and classification
Milianleo 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). Its orbit has an eccentricity of 0.13 and an inclination of 3° with respect to the ecliptic.[1] It was first observed as 2000 GE16 at Lincoln Laboratory ETS in 2000, extending the body's observation arc by 9 years prior to its official discovery at Tzec Maun.[2]
On 25 December 2098, Milianleo is expected to pass 4,449,642 kilometers from the asteroid 704 Interamnia.[1] It will pass it at a relative velocity of 7.12 kilometers per second.
Physical characteristics
Based on a generic absolute magnitude to diameter conversion, Milianleo measures approximately 2 kilometers in diameter, assuming an albedo of 0.10.[3] As of 2017, its spectral type as well as its rotation period and shape remain unknown.[1][4]
Naming
This minor planet was named after Milian Leo Schwab, the first-born son of German amateur astronomer and discoverer Erwin Schwab.[2][5] The approved naming citation was published by the Minor Planet Center 4 October 2009 (M.P.C. 67220).[6]
