Thora (minor planet designation: 299 Thora) is a 17 km Main belt asteroid with a potentially long 274-hour rotation period. It was discovered by Johann Palisa on 6 October 1890 in Vienna.
This object has a very low rate of spin, requiring 11.37 ± 0.04 days (272.9 ± 0.9 h) to complete a full rotation.
Lachesis is a large main-belt asteroid. It was discovered by French astronomer Alphonse Borrelly on April 10, 1872, and independently by German-American astronomer Christian Heinrich Friedrich Peters on April 11, 1872, then named after Lachesis, one of the Moirai, or Fates, in Greek mythology. A Lachesean occultation of a star occurred in 1999 and was confirmed visually by five observers and once photoelectrically, with the chords yielding an estimated elliptical cross-section of 184 × 144 km.
Arete is an asteroid in the asteroid belt. It has a very bright surface, even so when compared to other rocky S-type asteroid.
Weringia is a typical main-belt asteroid. It was discovered by Johann Palisa on 19 July 1882, and was named after Währing, part of Vienna, the city where the asteroid was discovered. Photometric observations during 2008 showed a rotation period of 11.1496 ± 0.0009 hours and a brightness variation of 0.20 ± 0.02 in magnitude.
Tyche is a relatively large main belt asteroid discovered by Robert Luther at Düsseldorf-Bilk Observatory on 4 May 1886. The stony S-type asteroid measures about 65 kilometers in diameter and has a perihelion of 2.1 AU.
Sapientia is a very large Main belt asteroid that was discovered by Johann Palisa on 15 April 1888 in Vienna. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
333 Badenia is a large background asteroid, approximately 72 kilometers in diameter, located the outer region of the asteroid belt. It was discovered on 22 August 1892, by astronomer Max Wolf at the Heidelberg-Königstuhl State Observatory in southwest Germany. The carbonaceous C-type asteroid has a rotation period of 9.9 hours. It was named after the historical Grand Duchy of Baden that existed until 1918, and where the discovering observatory is located. Badenia was the first asteroid to receive a provisional designation.
Petrina is a minor planet orbiting the Sun.
Gryphia is an S-type asteroid belonging to the Flora family in the Main Belt. Its diameter is about 15 km and it has an albedo of 0.168.
839 Valborg is a mid-sized S-type Eunomian asteroid. Its diameter is about 20 km, its albedo of 0.353 is very high for an asteroid. Its rotation period is 10.366 hours.
829 Academia is a minor planet orbiting the Sun. The asteroid is roughly 44 km in diameter and has a low albedo. Photometric measurements of the asteroid made in 2005 at the Palmer Divide Observatory showed a light curve with a period of 7.891 ± 0.005 hours and a brightness variation of 0.44 ± 0.02 in magnitude.
1918 Aiguillon provisional designation 1968 UA, is a dark asteroid from the outer region of the asteroid belt, approximately 20 kilometers in diameter.
1818 Brahms, provisional designation 1939 PE, is an asteroid from the inner regions of the asteroid belt, approximately 6 kilometers in diameter. It was discovered on 15 August 1939, by German astronomer Karl Reinmuth at Heidelberg Observatory in southern Germany. The asteroid was named after composer Johannes Brahms.
2311 El Leoncito, provisional designation 1974 TA1, is a dark and reddish asteroid from the outer region of the asteroid belt, approximately 53 kilometers in diameter. The asteroid was discovered by astronomers at Félix Aguilar Observatory at the Leoncito Astronomical Complex in Argentina on 10 October 1974. It was later named after the discovering site.
3267 Glo, provisional designation 1981 AA, is an eccentric Phocaean asteroid and sizable Mars-crosser from the inner regions of the asteroid belt, approximately 6.4 kilometers in diameter. It was discovered on 3 January 1981, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, Arizona. It was later named after American astronomer Eleanor Helin.
3073 Kursk, provisionally known as 1979 SW11, is a stony Florian asteroid and synchronous binary system from the inner regions of the asteroid belt, approximately 4.7 kilometers in diameter. It was discovered on 24 September 1979, by Soviet astronomer Nikolai Chernykh at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula.
3074 Popov, provisional designation 1979 YE9, is a carbonaceous Nysian asteroid from the inner regions of the asteroid belt, approximately 10 kilometers (6 miles) in diameter. It was discovered on 24 December 1979, by Soviet–Russian astronomer Lyudmila Zhuravleva at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula. The B-type asteroid has an unknown rotation period. It was named after Russian physicist Alexander Stepanovich Popov, an early radio pioneer in Russia.
