Gordonia (minor planet designation: 305 Gordonia) is a fairly typical, although sizeable Main belt asteroid. [3]
It was discovered by Auguste Charlois on 16 February 1891 in Nice and named after James Gordon Bennett Jr., his patron.
The light curve of 305 Gordonia shows a periodicity of 12.89 ± 0.01 hours, during which time the brightness of the object varies by 0.17 ± 0.03 in magnitude. [2]
Adria is a fairly large main-belt asteroid that was discovered by Austrian astronomer Johann Palisa on 23 February 1875, at the Austrian Naval Observatory, and named after the Adriatic Sea, on the coast of which the discovery was made. This dark-coloured asteroid has probably a primitive carbonaceous chondritic composition.
Russia is a large Main belt asteroid. It is classified as a C-type asteroid and is probably composed of primitive carbonaceous material. It was discovered by Johann Palisa on 31 January 1883 in Vienna, who named it after the country of Russia.
Walpurga is a large Main belt asteroid. It was discovered by Johann Palisa on 3 April 1886 in Vienna and was named after Saint Walburga.
Valda is a main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 3 November 1886 in Vienna. The name was proposed by Bettina von Rothschild.
Nike is a sizeable asteroid of the asteroid belt. It was discovered by Auguste Charlois on 5 March 1891 while working at the Nice Observatory. Charlois named it after the Greek goddess of victory, as well as the Greek name for the city where it was discovered. Measurement of the light curve of this asteroid in 2000 indicates a rotation period of 7.902 ± 0.005 hours.
Fraternitas is a typical Main belt asteroid. It was discovered by Johann Palisa on 6 April 1891 in Vienna. The asteroid name is Latin for 'fraternity'; it was so named in order to commemorate the 25th anniversary of the Maturitätsprüfung Fraternity.
Goberta is a mid-sized Themistian asteroid that was discovered by French astronomer Auguste Charlois on 8 September 1891 in Nice.
Svea is an asteroid from the asteroid belt and the namesake of the small Svea family, approximately 81 kilometers in diameter. The C-type asteroid and is probably composed of carbonaceous material.
Fama is a typical main belt asteroid in orbit around the Sun. It was discovered by German astronomer Max Wolf on 13 October 1895 in Heidelberg.
Violetta is a minor planet orbiting the Sun that was discovered by German astronomer Max Wolf on 26 January 1905 in Heidelberg. In light of M. F. Wolf's penchant ca. 1905 for naming asteroids after operatic heroines, it is likely that 557 Violetta is named after the protagonist of Giuseppe Verdi's famous opera La Traviata.
Polyxena is a minor planet orbiting the Sun. This main belt asteroid was discovered on 27 March 1906 by German astronomer August Kopff at the Heidelberg observatory. It was named after the youngest daughter of Priam and Hecuba, king and queen of Troy during the Trojan War. 595 Polyxena is orbiting at a distance of 3.21 AU from the Sun, with an orbital eccentricity (ovalness) of 0.06 and a period of 5.75 yr (2,099.1 d). The orbital plane is inclined at an angle of 17.8° to the ecliptic.
607 Jenny is a minor planet, specifically an asteroid orbiting in the asteroid belt that was discovered by German astronomer August Kopff on September 18, 1906.
608 Adolfine is a minor planet, specifically an asteroid orbiting in the asteroid belt.
650 Amalasuntha is a minor planet orbiting the Sun that was discovered by German astronomer August Kopff on October 4, 1907, at Heidelberg. It was named after Amalasuntha, the queen of the Ostrogoths from 526 to 534 AD. The name may have been inspired by the asteroid's provisional designation 1907 AM.
707 Steina is a minor planet, specifically an asteroid orbiting in the asteroid belt.
710 Gertrud is a Themistian asteroid, which means it is a member of the Themis family of asteroids. It was discovered by Austrian astronomer Johann Palisa on 28 February 1911 from Vienna.
1187 Afra is a dark background asteroid from the central regions of the asteroid belt. It was discovered by German astronomer Karl Reinmuth at Heidelberg Observatory on 6 December 1929. The X-type asteroid has a rotation period of 14.1 hours and measures approximately 32 kilometers in diameter. The origin of the asteroid's name remains unknown.
1216 Askania, provisional designation 1932 BL, is a stony Florian asteroid from the inner regions of the asteroid belt, approximately 9 kilometers in diameter. It was discovered on 29 January 1932, by German astronomer Karl Reinmuth at Heidelberg Observatory in southwest Germany. It was named after the company Askania Werke, a German manufacturer of precision instruments.
1671 Chaika, provisional designation 1934 TD, is a background asteroid from the Astraea region in the central asteroid belt, approximately 10 kilometers in diameter. It was discovered on 3 October 1934, by Soviet astronomer Grigory Neujmin at the Simeiz Observatory on the Crimean peninsula. The assumed S-type asteroid has a rotation period of 3.8 hours. It was named for Soviet cosmonaut Valentina Tereshkova.
2094 Magnitka (prov. designation: 1971 TC2) is a Flora asteroid from the inner regions of the asteroid belt, approximately 12 kilometers (7.5 miles) in diameter. It was discovered on 12 October 1971, at and by the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula. The discovery has not been attributed to an observing astronomer. It was later named for the city of Magnitogorsk.
