3099 Hergenrother, provisional designation Template:Mp, is an asteroid from the outer region of the asteroid belt, approximately 15 kilometers in diameter. It was discovered on 3 April 1940, by Finnish astronomer Yrjö Väisälä at Turku Observatory in Southwest Finland,[1] and named after American astronomer Carl Hergenrother in 1996.[2]

Orbit and classification

Hergenrother orbits the Sun in the outer main-belt at a distance of 2.3–3.5 AU once every 4 years and 11 months (1,786 days). Its orbit has an eccentricity of 0.20 and an inclination of 15° with respect to the ecliptic.[3] The body's observation arc begins 6 days after its official discovery observation at Turku.[1]

Physical characteristics

Rotation period

In January 2008, a rotational lightcurve of Hergenrother was obtained from photometric observations by French amateur astronomer Pierre Antonini. Lightcurve analysis gave a rotation period of 24.266 hours with a brightness variation of 0.28 magnitude (U=2Script error: No such module "Check for unknown parameters".).[4]

Diameter and albedo

According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Hergenrother measures 14.73 kilometers in diameter and its surface has an albedo of 0.224,[5][6] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for carbonaceous asteroids of 0.057 and consequently calculates a diameter of 29.21 kilometers, as the lower the albedo, the larger the body's diameter at a certain absolute magnitude.[7]

Naming

This minor planet was named in honor of American astronomer Carl W. Hergenrother (born 1973). At Lunar and Planetary Laboratory, he has been a discoverer of minor planets with high inclinations during the Bigelow Sky Survey, precursor to the Catalina Sky Survey. The naming was proposed by MPC director Brian G. Marsden among others.[2] The official naming citation was published by the Minor Planet Center on 3 May 1996 (M.P.C. 27124Script error: No such module "Check for unknown parameters".).[8]
