“9321 Alexkonopliv”的意思、由来-开放百科全书

This minor planet was named after JPL-scientist Alex Konopliv (born 1960), an internationally recognized authority on the measurement of the gravitational field of Solar System bodies tracked by satellites in Earth's orbit. Various Mars missions used his gravity field determinations for the Red Planet.^[2] The official naming citation was published by the Minor Planet Center on 5 October 1998 ({{small|M.P.C. 32610}}).^[21]

Physical characteristics

Rotation period

In December 2010, a rotational lightcurve of Alexkonopliv was obtained from photometric observation at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of {{val|3.4268}} hours with a brightness variation of 0.19 magnitude ({{small|U=2}}).^[7]

Diameter and albedo

According to the survey carried out by NASA's space-based Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Alexkonopliv measures 10.3 kilometers in diameter and its surface has an albedo of 0.116,^[5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and calculates a diameter of 11.5 kilometers with an absolute magnitude of 13.43.^[3]

The asteroid was discovered on 5 January 1989, by Japanese astronomer Takuo Kojima at the YGCO Chiyoda Station, Japan.^[16] It was named for JPL-scientist Alex Konopliv.^[2] Orbit and classification Alexkonopliv is a non-family asteroid from the main belt's background population. It orbits the Sun in the outer asteroid belt at a distance of 2.3–3.9 AU once every 5 years and 6 months (2,004 days). Its orbit has an eccentricity of 0.26 and an inclination of 4° with respect to the ecliptic. In November 1977, it was first identified as {{mp\|1977 VZ\|1}} at the Purple Mountain Observatory, China, extending the body's observation arc by 12 years prior to its official discovery observation at Chiyoda Station.^[16] Naming This minor planet was named after JPL-scientist Alex Konopliv (born 1960), an internationally recognized authority on the measurement of the gravitational field of Solar System bodies tracked by satellites in Earth's orbit.
