23718 Horgos

23718 Horgos, provisional designation 1998 GO10, 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.[8] 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.[1]

    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.[8]

    Physical characteristics

    Horgos has been characterized as a stony S-type asteroid by PanSTARRS photometric survey.[7]

    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 (U=2).[6]

    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.[4][5] 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.[3]

    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 (M.P.C. 43048).[9]

    gollark: Probably, people will vote for the shiny things at the expense of actually making anything work, and either there will be constant budget shortfalls and broken services, or the civil service will just take over everything.
    gollark: People voted for Trump. Direct democracy does not guarantee sanity.
    gollark: I agree. Counting is WRONG. We will just think about what looks most popular.
    gollark: For private repos, maybe?
