1930 Lucifer, provisional designation Template:Mp, is a carbonaceous asteroid from the outer regions of the asteroid belt, approximately 34 kilometers in diameter. It was discovered on 29 October 1964, by American astronomer Elizabeth Roemer at the Flagstaff station (NOFS) of the United States Naval Observatory (USNO).[1] It is named after Lucifer, the "shining one" or "light-bearer" from the Hebrew Bible.
Orbit
Lucifer orbits the Sun in the outer main-belt at a distance of 2.5–3.3 AU once every 4 years and 11 months (1,802 days). Its orbit has an eccentricity of 0.14 and an inclination of 14° with respect to the ecliptic.[2] It was first identified as Template:Mp at Goethe Link Observatory in 1954, extending the body's observation arc by 10 years prior to its official discovery observation at NOFS.[1]
Physical characteristics
Spectral type
In the SMASS taxonomy, Lucifer is a Cgh-type that belongs to the carbonaceous C-group of asteroids.[2]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite, and NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Lucifer measures between 27.00 and 39.61 kilometers in diameter, and its surface has an albedo between 0.05 and 0.1058.[3][4][5][6][7][8] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0886 and calculates a diameter of 26.90 kilometers based on an absolute magnitude of 11.1.[9]
Rotation and pole axis
In October 2003, a rotational lightcurve of Lucifer was obtained from photometric observations by American astronomer Brian Warner at his Palmer Divide Observatory in Colorado. Lightcurve analysis gave a well-defined rotation period of 13.056 hours with a brightness amplitude of 0.44 magnitude (U=3Script error: No such module "Check for unknown parameters".).[10]
In January 2005, observations by astronomer Horacio Correia gave a concurring period of 13.054 hours and an amplitude of 0.22 magnitude (U=3Script error: No such module "Check for unknown parameters".).[11] In 2013, another lightcurve was obtained at the Palomar Transient Factory (U=2Script error: No such module "Check for unknown parameters".),[12] and a modeled lightcurve from various data sources, including the AstDyS database, gave another concurring period of 13.0536 hours and found a pole of (32.0°,17.0°).[13]
Naming
Lutz D. Schmadel's Dictionary of Minor Planet Names reads "Named for the proud, rebellious archangel, identified with Satan, who was expelled from heaven".[14] The official Template:MoMP was published by the Minor Planet Center on 1 August 1978 (M.P.C. 4419Script error: No such module "Check for unknown parameters".).[15]
