Английская Википедия:23718 Horgos
23718 Horgos, provisional designation Шаблон:Mp, is a stony background asteroid from the central regions of the asteroid belt, approximately 2.9 kilometers in diameter. It was discovered on 2 April 1998, by Hungarian astronomers Krisztián Sárneczky and László Kiss at Konkoly's Piszkéstető Station northeast of Budapest, Hungary.[1] The asteroid was named after the Serbian town of Horgoš.[2]
Orbit and classification
Horgos is a non-family from the main belt's background population. It orbits the Sun in the central main belt at a distance of 2.1–3.1 AU once every 4 years and 1 month (1,501 days). Its orbit has an eccentricity of 0.19 and an inclination of 1° with respect to the ecliptic.[3]
The body's observation arc begins with a precovery taken by Spacewatch at Kitt Peak Observatory in November 1995, or 29 months prior to its official discovery observation at Piszkéstető.[1]
Physical characteristics
Horgos has been characterized as a stony S-type asteroid by PanSTARRS photometric survey.[4]
Rotation period
In January 2014, a rotational lightcurve of Horgos was obtained from photometric observations in the R-band by astronomers at the Palomar Transient Factory in California. Lightcurve analysis gave a rotation period of 3.57 hours with a brightness amplitude of 0.21 magnitude (Шаблон:Small).[5]
Diameter and albedo
According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Horgos measures 2.944 kilometers in diameter and its surface has an albedo of 0.269.[6][7] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 2.79 kilometers based on an absolute magnitude of 15.14.[8]
Naming
This minor planet was named after the village of Horgoš, now in northern Serbia. The village is located near the Hungarian border and has a large Hungarian population. It is also the place where the second discoverer László L. Kiss grew up.[2] The official naming citation was published by the Minor Planet Center on 5 July 2001 (Шаблон:Small).[9]
