1825 Klare (prov. designation: 1954 QH) is a background asteroid from the central region of the asteroid belt, approximately 15 kilometers in diameter. It was discovered on 31 August 1954, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany. [13] The asteroid was named after Heidelberg astronomer Gerhard Klare. [2]
The presumably stony asteroid orbits the Sun in the central main-belt at a distance of 2.4–3.0 AU once every 4 years and 5 months (1,600 days). Its orbit has an eccentricity of 0.11 and an inclination of 4° with respect to the ecliptic. [1] First identified as 1934 CH at Uccle Observatory in 1934, Klare's observation arc begins 20 years prior to its official discovery observation. [13]
Klare was named after Gerhard Klare (born 1932), an observing astronomer at Heidelberg Observatory since 1960, whose fields of interest include minor planets. [2] He is also known for his numerous contributions in the yearbook series "Reviews in Modern Astronomy" of the Astronomische Gesellschaft. The official naming citation was published by the Minor Planet Center on 18 April 1977 ( M.P.C. 4156). [14]
Klare has been the subject of multiple photometric lightcurve studies, which gave a well-determined rotation period between 4.741 and 4.744 hours with a brightness variation between 0.70 and 0.90 magnitude ( U=3/n.a. ). [5] [7] [8] [9] [10] [11] Measurements have also been used as the basis for generating a three-dimensional model of its shape. [6] The Collaborative Asteroid Lightcurve Link (CALL) adopts a period 4.744 hours with an amplitude of 0.70 magnitude ( U=3 ). [3]
According to the survey carried out by the Japanese Akari satellite, Klare measures 14.69 kilometers in diameter, and its surface has an albedo of 0.167, [4] while CALL assumes an albedo of 0.10 – a compromise value for asteroids with a semi-major axis between 2.6 and 2.7 AU, for which neither a S (0.20) nor a C (0.057) type has been determined – and calculates a diameter of 19.21 kilometers with an absolute magnitude of 11.7.

Scylla is a main belt asteroid. It was discovered by Austrian astronomer Johann Palisa at the Austrian Naval Observatory on 8 November 1875, and named after the monster Scylla in Greek mythology. Two weeks after its discovery this asteroid became lost and was not recovered for 95 years. It was finally found by Paul Wild of Berne, Switzerland with the aid of an ephemeris created in 1970 by Conrad M. Bardwell at Cincinnati Observatory.

It was discovered on 18 April 1915, by German astronomer Max Wolf at Heidelberg Observatory in southern Germany. The discovery observation was ignored for orbital determination, with the first used observation made at Vienna Observatory on 1 May 2015, reducing the asteroid's observation arc by 2 weeks.

It was discovered by German astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory on 28 January 1917.

It was discovered by German astronomer Max Wolf at the Heidelberg Observatory on 30 November 1918. The uncommon L-type asteroid has a rotation period of 14.6 hours. It was named after Buda, the smaller part of the Hungarian city of Budapest.
978 Aidamina, provisional designation 1922 LY, is a dark background asteroid from the outer region of the asteroid belt, approximately 79 kilometers in diameter. It was discovered by astronomer Sergey Belyavsky in 1922, and later named after Aida Minaevna, a friend of the discoverer's family.
1741 Giclas is a stony Koronis asteroid from the outer region of the asteroid belt, approximately 13 kilometers in diameter. It was discovered on 26 January 1960, by IU's Indiana Asteroid Program at Goethe Link Observatory near Brooklyn, Indiana, United States. It is named for astronomer Henry L. Giclas.
