914 Palisana, provisional designation 1919 FN, is a Phocaean asteroid from the inner regions of the asteroid belt, approximately 77 kilometers in diameter. It was discovered by German astronomer Max Wolf at Heidelberg Observatory on 4 July 1919. [10]
The carbonaceous asteroid is classified as a CU-type on the Tholen taxonomic scheme. It orbits the Sun at a distance of 1.9–3.0 AU once every 3 years and 10 months (1,407 days). Its orbit has an eccentricity of 0.21 and an inclination of 25° with respect to the ecliptic. [3]
Measurements using the adaptive optics at the W. M. Keck Observatory give a diameter estimate of 76 km. The size ratio between the major and minor axes is 1.16. [4] During 2004, the asteroid was observed occulting a star. The resulting chords were used to determine a diameter estimate of 91.2 km. This is a poor match to the diameter determined by other means. [11]
The minor planet is named after the Austrian astronomer Johann Palisa (1848–1925), who has discovered many asteroids himself between 1874 and 1923. [1]
Amphitrite is one of the largest S-type asteroids, approximately 200 kilometers in diameter, and probably fifth largest after Eunomia, Juno, Iris and Herculina.
Camilla is one of the largest asteroids from the outermost edge of the asteroid belt, approximately 250 kilometers in diameter. It is a member of the Sylvia family and located within the Cybele group. It was discovered on 17 November 1868, by English astronomer Norman Pogson at Madras Observatory, India, and named after Camilla, Queen of the Volsci in Roman mythology. The X-type asteroid is a rare trinary asteroid with two minor-planet moons discovered in 2001 and 2016, respectively. It is elongated in shape and has a short rotation period of 4.8 hours.
Elsa is a Massalia or background asteroid from the inner regions of the asteroid belt, approximately 44 kilometers in diameter. It was discovered on 7 February 1878, by Austrian astronomer Johann Palisa at the Austrian Naval Observatory in today's Croatia. The S-type asteroid has a very long rotation period of 80 hours and likely an elongated shape. The origin of its name is uncertain.
Istria is a stony background asteroid from the central regions of the asteroid belt, approximately 33 kilometers in diameter. It was discovered on 8 February 1878, by Austrian astronomer Johann Palisa at the Austrian Naval Observatory in Pola, in what is now Croatia. The S-type asteroid has a rotation period of 11.77 hours. It was named for the Istrian Peninsula.
Stephania is a dark background asteroid from the inner regions of the asteroid belt, approximately 32 km (20 mi) in diameter. It was discovered on 19 May 1881, by Austrian astronomer Johann Palisa at the Vienna Observatory. The C-type asteroid has a rotation period of 18.2 hours. It was named after Princess Stéphanie of Belgium.
Hercynia, provisional designation 1900 FK, is a background asteroid from the outer regions of the asteroid belt, approximately 38 kilometers in diameter. It was discovered on 21 September 1900, by astronomers Max Wolf and Arnold Schwassmann at the Heidelberg-Königstuhl State Observatory in southwest Germany. The asteroid was named for the ancient Hercynian Forest, known to the Romans as "Hercynia silva".
Lagrangea, provisional designation 1923 OU, is a carbonaceous background asteroid from the outer region of the asteroid belt, approximately 30 kilometers in diameter. It was discovered on 12 September 1923, by Russian astronomer Sergey Belyavsky at the Simeiz Observatory on the Crimean peninsula. The asteroid was named after Italian mathematician and astronomer Joseph-Louis Lagrange.
1018 Arnolda, provisional designation 1924 QM, is a stony asteroid from the central regions of the asteroid belt, approximately 16 kilometers in diameter. It was discovered on 3 March 1924, by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southwest Germany. The asteroid was named after physicist Arnold Berliner.
1043 Beate, provisional designation 1925 HB, is a stony asteroid from the outer region of the asteroid belt, approximately 32 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory on 22 April 1925. Any reference of its name to a person is unknown.
1086 Nata, provisional designation 1927 QL, is a carbonaceous Veritasian asteroid from the outer regions of the asteroid belt, approximately 68 kilometers in diameter. It was discovered on 25 August 1927, by Russian astronomers Sergey Belyavsky and Nikolaj Ivanov at the Simeiz Observatory on the Crimean peninsula. The asteroid was named in memory of Soviet female parachutist Nata Babushkina (1915–1936).
1099 Figneria, provisional designation 1928 RQ, is an asteroid from the background population of the outer regions of the asteroid belt, approximately 26 kilometers in diameter. Discovered by Grigory Neujmin at Simeiz Observatory in 1928, the asteroid was later named after Russian revolutionary activist Vera Figner.
1128 Astrid, provisional designation 1929 EB, is a carbonaceous Astridian asteroid from the central region of the asteroid belt. It is the parent body of the Astrid family and measures approximately 40 kilometers in diameter.
