Huenna (minor planet designation: 379 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.
It was discovered by Auguste Charlois on 8 January 1894 in Nice. It is the Latin name for the Swedish island of Ven, the site of two observatories. This island is where Tycho Brahe built his observatory. [6]
A satellite, 7 km across and designated S/2003 (379) 1, was discovered on 14 August 2003 by Jean-Luc Margot using the Keck II adaptive optics telescope at Mauna Kea. [7] The moon orbits 3400±11 km away in 80.8±0.36 d with an eccentricity of 0.334±0.075. [5] The system is loosely bound [4] as Huenna has a Hill sphere with a radius of about 20,000 km. [2]
Antiope is a double asteroid in the outer asteroid belt. It was discovered on October 1, 1866, by Robert Luther. In 2000, it was found to consist of two almost-equally-sized bodies orbiting each other. At average diameters of about 88 km and 84 km, both components are among the 500 largest asteroids. Antiope is a member of the Themis family of asteroids that share similar orbital elements.
Eugenia is a large asteroid of the asteroid belt. It is famed as one of the first asteroids to be found to have a moon orbiting it. It was also the second triple asteroid to be discovered, after 87 Sylvia.
216 Kleopatra is a large M-type asteroid with a mean diameter of 120 kilometers and is noted for its elongate bone or dumbbell shape. It was discovered on 10 April 1880 by Austrian astronomer Johann Palisa at the Austrian Naval Pola Observatory, in what is now Pula, Croatia, and was named after Cleopatra, the famous Egyptian queen. It has two small minor-planet moons which were discovered in 2008 and later named Alexhelios and Cleoselene.
Hermione is a very large binary asteroid discovered in 1872. It orbits in the Cybele group in the far outer asteroid belt. As an asteroid of the dark C spectral type, it is probably composed of carbonaceous materials. In 2002, a small moon was found to be orbiting Hermione.
Kalliope is a large M-type asteroid from the asteroid belt discovered by J. R. Hind on 16 November 1852. It is named after Calliope, the Greek Muse of epic poetry. It is orbited by a small moon named Linus.
Nausikaa is a large main-belt S-type asteroid. It was discovered by Johann Palisa on February 17, 1879, at Pula, then in Austria, now in Croatia. The name derives from Nausicaä, a princess in Homer's Odyssey.
Ampella is a Main belt asteroid that was discovered by Alphonse Borrelly on June 13, 1879. The name seems to be the feminine form of Ampelos, a satyr and good friend of Dionysus in Greek mythology. It could also derive from the Ampelose, a variety of hamadryad. It is an S-type asteroid.
283 Emma is a large asteroid of the asteroid belt and the namesake of the Emma family. It was discovered by Auguste Charlois on 8 February 1889, in Nice, France. The reason for its name is unknown.
654 Zelinda is a minor planet orbiting the Sun that was discovered on 4 January 1908 by German astronomer August Kopff. On favorable oppositions, it can be as bright as magnitude 10.0, as on January 30, 2016.
3749 Balam is a stony Flora asteroid and rare trinary system orbiting in the inner regions of asteroid belt. It also forms a secured asteroid pair with sub-kilometer sized asteroid (312497) 2009 BR60. Balam was discovered on 24 January 1982, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station near Flagstaff, Arizona, and received the prov. designation 1982 BG1. It was named after Canadian astronomer David Balam. Balam measures approximately 4.1 kilometers (2.5 miles) in diameter. Its two minor-planet moons have an estimated diameter of 1.66 and 1.84 kilometers, respectively.
4492 Debussy is a dark and elongated background asteroid and binary system from the intermediate asteroid belt, approximately 15 kilometers in diameter. It was discovered on 17 September 1988, by Belgian astronomer Eric Elst at Haute-Provence Observatory in France. It was later named after French composer Claude Debussy.
3782 Celle, provisional designation 1986 TE, is a bright Vestian asteroid and asynchronous binary system from the inner regions of the asteroid belt, approximately 6.5 kilometers in diameter. It was discovered on 3 October 1986, by Danish astronomer Poul Jensen at the Brorfelde Observatory in Denmark and named after the German city of Celle. The V-type asteroid has a rotation period of 3.84 hours. The discovery of its 2.3-kilometer minor-planet moon was announced in 2003.
1333 Cevenola, provisional designation 1934 DA, is a binary Eunomian asteroid from the asteroid belt, approximately 15 kilometers in diameter. It was discovered on 20 February 1934, by French astronomer Odette Bancilhon at Algiers Observatory, Algeria in Northern Africa. It was named after the French mountain-range Cévennes, via the Occitan feminine adjective/demonym cevenòla.
3034 Climenhaga is a stony Florian asteroid and synchronous binary asteroid from the inner regions of the asteroid belt, approximately 7.8 kilometers in diameter. The asteroid was discovered on 24 September 1917 by German astronomer Max Wolf at Heidelberg Observatory in southwest Germany and assigned provisional designation A917 SE. It was later named after Canadian astrophysicist John Climenhaga. Its minor-planet moon has a period of nearly 19 hours.
9069 Hovland, provisional designation 1993 OV, is a stony binary Hungaria asteroid from the inner regions of the asteroid belt, approximately 3 kilometers in diameter.
6244 Okamoto, provisional designation 1990 QF, is a background asteroid and binary system from the inner regions of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 20 August 1990, by Japanese astronomer Tsutomu Seki at the Geisei Observatory in Kōchi, Japan, and later named after Japanese school teacher Hiroshi Okamoto. The presumed S-type asteroid has a short rotation period of 2.9 hours. The discovery of its minor-planet moon was announced in October 2006.
4383 Suruga, provisional designation 1989 XP, is a Vestian asteroid and binary system from the inner regions of the asteroid belt, approximately 6.5 kilometers in diameter. It was discovered on 1 December 1989, by Japanese astronomer Yoshiaki Oshima at Gekko Observatory, Japan. The asteroid was named after the former Japanese Suruga Province. Its synchronous minor-planet moon, S/2013 (4383) 1, measures approximately 1.33 kilometers and has a period of 16.386 hours.
5477 Holmes, provisional designation 1989 UH2, is a Hungaria asteroid and binary system from the innermost regions of the asteroid belt, approximately 3 kilometers (2 miles) in diameter. It was discovered on 27 October 1989, by American astronomer Eleanor Helin at the Palomar Observatory in California. The presumed E-type asteroid is likely spherical in shape and has a short rotation period of 2.99 hours. It was named for American amateur astronomer Robert Holmes. The discovery of its 1-kilometer-sized minor-planet moon was announced in November 2005.
22899 Alconrad, provisional designation 1999 TO14, is a Koronian asteroid and binary system from the outer region of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 11 October 1999, by Croatian astronomers Korado Korlević and Mario Jurić at the Višnjan Observatory, Croatia.
(300163) 2006 VW139, provisional designations 2006 VW139 and P/2006 VW139, as well as periodic cometary number 288P, is a kilometer-sized asteroid from the outer regions of the asteroid belt and the first "binary main-belt comet" ever discovered.
