Ilmatar (minor planet designation: 385 Ilmatar) is a large main belt asteroid.
It was discovered by Max Wolf on March 1, 1894, in Heidelberg. [3] It was named after Ilmatar, virgin spirit of the air from the Finnish epic Kalevala . Its mass has been estimated as (1.039 ± 0.515/0.201)×1018 kg. [2] Its rotation is 62.35 hr.
2934 Aristophanes, provisional designation 4006 P-L, is a carbonaceous Veritasian asteroid from the outer regions of the asteroid belt, approximately 22 kilometers in diameter. It was discovered during the Palomar–Leiden survey in 1960, and later named after ancient Greek dramatist Aristophanes.
Koronis is a main-belt asteroid that was discovered by Russian astronomer Viktor Knorre on January 4, 1876, from the Berlin observatory. It was the first of his four asteroid discoveries. The meaning of the asteroid name is uncertain, but it may come from Coronis the mother of Asclepius from Greek mythology. Alternatively, it may come from Coronis, a nymph of the Hyades sisterhood. The Koronis family is named after this asteroid.
May is a large Main belt asteroid. It was discovered by Auguste Charlois on 28 November 1892 in Nice, and was named for the German author Karl May. This asteroid is orbiting the Sun at a distance of 2.97 AU with a period of 5.12 years and an eccentricity (ovalness) of 0.067. The orbital plane is inclined at an angle of 9.7° to the plane of the ecliptic. During its orbit, this asteroid has made close approaches to the dwarf planet Ceres. For example, in September 1984 the two were separated by 6.3 Gm (0.042 AU).
Huenna is a large asteroid orbiting in the asteroid belt. It is part of the Themis family, and thus a C-type asteroid and consequently composed mainly of carbonaceous material.
380 Fiducia is a dark and large asteroid, approximately 68 kilometers in diameter, located in the central region of the asteroid belt. It was discovered by French astronomer Auguste Charlois at the Nice Observatory on 8 January 1894. The carbonaceous C-type asteroid has a rotation period of 13.7 hours. It was named "Fiducia", the Latin word for confidence.
Janina is a Themistian asteroid, approximately 46 kilometers in diameter. It is spectral B-type and is probably composed of primitive carbonaceous chondritic material.
Burdigala is a typical Main belt asteroid. It was discovered by F. Courty on 11 February 1894 in Bordeaux. It was the first of his two asteroid discoveries. The other was 387 Aquitania. Burdigala is the Latin name of the city of Bordeaux.
Alma is an asteroid from the intermediate asteroid belt, approximately 24 kilometers in diameter. It was Guillaume Bigourdan's only asteroid discovery. He discovered it on 24 March 1894 in Paris.
Delia is a large Main belt asteroid. It was discovered by the French astronomer Auguste Charlois on 30 November 1894 in Nice. "Delia" is an epithet for the ancient Greco-Roman Moon goddess Artemis, for her birthplace at Delos. This asteroid is orbiting the Sun at a distance of 2.79 AU with an orbital eccentricity (ovalness) of 0.085 and a period of 4.64 yr. The orbital plane is tilted at an angle of 3.35° to the plane of the ecliptic.
Aeolia is a typical main belt asteroid. It was discovered by the French astronomer Auguste Charlois on 1 December 1894 from Nice, and may have been named for the ancient land of Aeolis. The asteroid is orbiting the Sun at a distance of 2.74 AU with a period of 4.54 years and an eccentricity (ovalness) of 0.16. The orbital plane is inclined at an angle of 2.5° to the plane of the ecliptic. This is the largest member of the eponymously named Aeolia asteroid family, a small group of asteroids with similar orbits that have an estimated age of less than 100 million years.
Vienna is a typical Main belt asteroid. It was discovered by French astronomer Auguste Charlois on 19 December 1894 in Nice, and was most likely named after the city of Vienna, Austria. This object is orbiting the Sun at a distance of 2.64 AU with an orbital eccentricity (ovalness) of 0.246 and a period of 4.28 yr. The orbital plane is inclined at an angle of 12.85° to the ecliptic.
Admete, provisional designation 1894 BN, is a dark, carbonaceous asteroid from the outer region of the asteroid belt, about 47 kilometers in diameter. It was discovered on 28 December 1894, by French astronomer Auguste Charlois at Nice Observatory in southeastern France.
Tauntonia is a dark Alauda asteroid from the outer region of the asteroid belt, approximately 61 kilometers in diameter.
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.
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.
2010 Chebyshev, provisional designation 1969 TL4, is a rare-type carbonaceous asteroid from the outer regions of the asteroid belt, approximately 25 kilometers in diameter. The asteroid was discovered on 13 October 1969, by Soviet astronomer Bella Burnasheva at the Crimean Astrophysical Observatory in Nauchnyj, on the Crimean peninsula. It was named for mathematician Pafnuty Chebyshev.
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.
11573 Helmholtz, provisional designation 1993 SK3, is a Zhongguo asteroid from the outermost region of the asteroid belt, approximately 13 kilometers (8 miles) in diameter. It was discovered on 20 September 1993, by German astronomers Freimut Börngen and Lutz Schmadel at the Karl Schwarzschild Observatory in Tautenburg, Germany. It is one of few asteroids located in the 2:1 resonance with Jupiter. The asteroid was named for German physicist Hermann von Helmholtz.
116903 Jeromeapt is an asteroid of the Massalia family from the inner regions of the asteroid belt, approximately 1.1 kilometers in diameter. It was discovered on 11 April 2004, by American astronomer Jim Young at the Table Mountain Observatory near Wrightwood, California, in the United States. The asteroid was named for American astronaut Jerome Apt.
