143 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.
One occultation by Adria has been reported so far, from Japan on August 21, 2000. A somewhat spherical shape measuring 98 × 86 km was observed.
Photometric observations of this asteroid made during 2008 at the Organ Mesa Observatory in Las Cruces, New Mexico gave an irregular light curve with a period of 22.005 ± 0.001 hours and a brightness variation of 0.08 ± 0.01 in magnitude. [5]
26 Proserpina is a main-belt asteroid discovered by German astronomer R. Luther on May 5, 1853. It is named after the Roman goddess Proserpina, the daughter of Ceres and the Queen of the Underworld. Another main-belt asteroid, 399 Persephone, discovered in 1895, is named after her Greek counterpart. Its historical symbol was a star inside a pomegranate; it is in the pipeline for Unicode 17.0 as U+1CECD .
151 Abundantia is a stony main belt asteroid. It was discovered by Johann Palisa on 1 November 1875, from the Austrian Naval Observatory in Pula. The name was chosen by Edmund Weiss of the Vienna Observatory; although the name refers to Abundantia, a Roman goddess of luck, it was also chosen to celebrate the increasing numbers of asteroids that were being discovered in the 1870s.
167 Urda is a main-belt asteroid that was discovered by German-American astronomer Christian Heinrich Friedrich Peters on August 28, 1876, in Clinton, New York, and named after Urd, one of the Norns in Norse mythology. In 1905, Austrian astronomer Johann Palisa showed that the asteroid varied in brightness.
188 Menippe is a main belt asteroid. The object has a bright surface and rocky composition. It was discovered by C. H. F. Peters on June 18, 1878, in Clinton, New York, and named after Menippe, one of the daughters of Orion in Greek mythology.
224 Oceana is an asteroid from the asteroid belt. It was discovered by Austrian astronomer Johann Palisa on 30 March 1882, in Vienna. It was named after the Pacific Ocean. Based upon its spectrum, it is classified as an M-type asteroid, but is not metallic.
225 Henrietta is a very large outer main-belt asteroid. It was discovered by Austrian astronomer Johann Palisa on April 19, 1882, in Vienna and named after Henrietta, wife of astronomer Pierre J. C. Janssen. The asteroid is orbiting at a distance of 3.39 AU from the Sun with a period of 6.24 years and an eccentricity (ovalness) of 0.26. The orbital plane is inclined at an angle of 20.9° to the plane of the ecliptic. 225 Henrietta belongs to Cybele group of asteroids and is probably in a 4:7 orbital resonance with the planet Jupiter.
235 Carolina is a sizeable Main belt asteroid. It was discovered by Austrian astronomer Johann Palisa on 28 November 1883 in Vienna, and was named after Caroline Island, now part of Kiribati in the Pacific Ocean. This asteroid is orbiting the Sun at a distance of 2.88 AU with a period of 4.89 yr and an eccentricity (ovalness) of 0.06. The orbital plane is tilted at an angle of 9.0° to the plane of the ecliptic.
242 Kriemhild is a main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 22 September 1884 in Vienna and was named after Kriemhild, a mythological Germanic princess, by Moriz von Kuffner, a Viennese industrialist and sponsor of astronomy.
272 Antonia is a main belt asteroid that was discovered by French astronomer Auguste Charlois on 4 February 1888 in Nice.
273 Atropos is a typical Main belt asteroid that was discovered by Austrian astronomer Johann Palisa on 8 March 1888 in Vienna.
400 Ducrosa is a typical Main belt asteroid. It was discovered by Auguste Charlois on 15 March 1895 in Nice.
595 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.
639 Latona is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered by German astronomer Karl Lohnert on July 19, 1907, at Heidelberg.
687 Tinette is a minor planet, specifically an asteroid orbiting primarily in the asteroid belt. It was discovered by Austrian astronomer Johann Palisa on 16 August 1909 from Vienna and was given the preliminary designation 1909 HG.
708 Raphaela is a minor planet orbiting the Sun.
793 Arizona is a minor planet orbiting the Sun that was discovered April 9, 1907 by American businessman Percival Lowell at Flagstaff. It was named for the state of Arizona. The object was independently discovered on April 17, 1907, by J. H. Metcalf at Taunton. This is a main belt asteroid orbiting 2.8 AU from the Sun with a period of 4.675 yr and an eccentricity (ovalness) of 0.13. The orbital plane is inclined at an angle of 15.8° to the plane of the ecliptic.
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.
947 Monterosa is a minor planet orbiting the Sun.
8441 Lapponica, provisional designation 4008 T-3, is a background asteroid from the Florian region of the inner asteroid belt, approximately 4.5 kilometers in diameter. It was discovered on 16 October 1977, by Ingrid and Cornelis van Houten at Leiden, and Tom Gehrels at Palomar Observatory in California. The L-type asteroid has a rotation period of 3.27 hours. It was named for the Bar-tailed godwit, a shorebird also known by its Latin name Limosa lapponica.
