1710 Gothard, provisional designation 1941 UF, is a stony asteroid from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 20 October 1941, by Hungarian astronomer György Kulin at the Konkoly Observatory in Budapest, Hungary.[7] It was later named after Hungarian amateur astronomer Jenő Gothard.[2]
Orbit and classification
The S-type asteroid orbits the Sun at a distance of 1.7–2.9 AU once every 3 years and 6 months (1,292 days). Its orbit has an eccentricity of 0.27 and an inclination of 8° with respect to the ecliptic.[1] Gothard's observation arc begins 14 years after its official discovery observation, when it was identified as 1955 TT at Uccle Observatory in 1955.[7]
Physical characteristics
Rotation period
In October 2001 and October 2008, two rotational light-curves of Gothard were obtained by French amateur astronomers Laurent Bernasconi and René Roy, giving a concurring rotation period of 4.94 hours with a brightness variation of 0.31 and 0.32 in magnitude, respectively ({{{1}}}).[6]
Diameter and albedo
According to the survey carried out by NASA's Wide-field Infrared Survey Explorer with its subsequent NEOWISE mission, Gothard measures 9.84 kilometers in diameter, and its surface has an albedo of 0.087,[4][5] while the Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 5.66 kilometers with an absolute magnitude of 13.6.[3]
Naming
This minor planet was named in memory of Hungarian amateur astronomer Jenő Gothard (1857–1909), who discovered the central star in the Ring Nebula (M57).[2] The official naming citation was published by the Minor Planet Center on 1 February 1980 (M.P.C. 5183).[8]
