“1951 Lick”的意思、由来-开放百科全书

The asteroid orbits the Sun at a distance of 1.3–1.5 AU once every 20 months (599 days). Its orbit has an eccentricity of 0.06 and an inclination of 39° with respect to the ecliptic. Lick{{'}}s observation arc begins with its discovery observation, as no precoveries were taken, and no prior identifications were made.^[4]

Physical characteristics

Spectral type

In the SMASS taxonomic scheme, Lick{{'}}s spectral type is that of a rare A-type asteroid with a surface consisting of almost pure olivine.^[26] As of 2016, only 17 minor planets of this type are known.^[27]

Rotation period

In July 2008, a rotational lightcurve was obtained from photometric by astronomer Brian D. Warner at his Palmer Divide Observatory in Colorado, United States. It gave a well-defined rotation period of 5.2974 hours with a brightness variation of 0.25 in magnitude ({{small|U=3}}).^[10] Several lightcurves with a lower or unassessed quality have been obtained by astronomers Wiesław Z. Wiśniewski and Petr Pravec in the 1980s and 1990s.^[9]{{efn|name=LCDB-Pravec-1998}}{{efn|name=LCDB-Pravec-1997}} The most recent observation by Michael Lucas in February 2011, gave a period of 5.317 hours with an amplitude of 0.33 magnitude ({{small|U=2}}).^[11]

Diameter and albedo

According to 3 observations taken by the Infrared Astronomical Satellite IRAS, Lick measures 5.57 kilometers in diameter and its surface has an albedo of 0.09.^[7] The Collaborative Asteroid Lightcurve Link agrees with the results obtained by IRAS and derives an albedo of 0.10 and a diameter of 5.59 kilometers with an absolute magnitude of 14.35.^[5]
