Gotha Observatory ( Seeberg Observatory , Sternwarte Gotha or Seeberg-Sternwarte ) was a German astronomical observatory located on Seeberg hill near Gotha , Thuringia , Germany . Initially the observatory was dedicated to astrometry , geodetic and meteorological observation and tracking the time.
13-531: The minor planet 1346 Gotha was named after the city of Gotha in recognition of the observatory. Planning for the observatory began in 1787 by the court astronomer Baron Franz Xaver von Zach , with the financing of Ernest II, Duke of Saxe-Gotha-Altenburg . It was based upon the Radcliffe Observatory in Oxford , England . The building was divided into five parts, with the central section holding
26-464: A theodolite ( Reichenbach , Utzschneider & Liebherr), a different heliometer ( Fraunhofer ), new mounting, and three-foot meridian circle (Ertel, Utzschneider & Fraunhofer ). No spectroscopy or photography was performed at the observatory and the only astrophysical equipment of the observatory was a Zöllner photometer . The observatory directors were as follows: 1346 Gotha 1346 Gotha , provisional designation 1929 CY ,
39-472: A brightness variation between 0.10 and 0.16 magnitude ( U=3- ). According to the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer , Gotha measures between 13.731 and 13.747 kilometers in diameter and its surface has an albedo between 0.278 and 0.2794. The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and derives

65-483: A revolving dome. There were two wings to provide quarters for the staff. During Peter Andreas Hansen 's term, the observatory was dismantled and moved to a less exposed location in Gotha. The observatory was closed in 1934. Around 1800, the observatory became an international center for astronomy, being the most modern astronomical institute primarily for its instruments. The instruments came from London , England ,

91-638: Is a stony background asteroid from the central regions of the asteroid belt , approximately 14 kilometers (8.7 mi) in diameter. It was discovered on 5 February 1929, by astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany. The presumed S-type asteroid has a short rotation period of 2.6 hours. It was named for the German city of Gotha , located in Thuringia . Based on
104-525: The ecliptic . The body's observation arc begins with its official discovery observation at Heidelberg in 1929. This minor planet was named after the city of Gotha , located near Erfurt capital of the Free State of Thuringia , Germany. The asteroids 1254 Erfordia and 934 Thüringia are also named after these places. The city is known for its Gotha Observatory and the work of astronomer Franz Xaver von Zach (1754–1832), who recovered
117-584: The hierarchical clustering method , Gotha is a non- family asteroid of the main belt's background population (Nesvorny), but it has also been considered a core member of the Eunomia family by Novakovic, Knezevic and Milani. It orbits the Sun in the central main-belt at a distance of 2.2–3.1 AU once every 4 years and 3 months (1,556 days; semi-major axis of 2.63 AU). Its orbit has an eccentricity of 0.18 and an inclination of 14 ° with respect to
130-566: The dwarf planet Ceres and after whom 999 Zachia was named. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 ( H 122 ). Gotha has been estimated to be a stony S-type asteroid . Several rotational lightcurves of Gotha have been obtained from photometric observations since 1984. Lightcurve analysis gave a consolidated rotation period of 2.64067 hours with
