184 Dejopeja is a large M-type Main belt asteroid. It was discovered by Johann Palisa on February 28, 1878, and was named after Deiopea, a Roman nymph. [2]
This is an X-type asteroid with a diameter of 66 km and a geometric albedo of 0.190. Based upon Photometric observations taken during 2000, it has a synodic rotation period of 6.441 ± 0.001 h. The light curve is tri-modal, most likely due to an angular shape, with a peak-to-peak amplitude of 0.19 ± 0.01 in magnitude. [3]
51826 Kalpanachawla (provisional designation 2001 OB34) is an Eoan asteroid in the outer region of the asteroid belt, approximately 7 kilometers in diameter. It was discovered on 19 July 2001, by astronomers of the Near-Earth Asteroid Tracking program at Palomar Observatory in California, United States. The asteroid was named for Indo-American astronaut and mission specialist Kalpana Chawla, who died in the Space Shuttle Columbia disaster.
120 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.
25924 Douglasadams (provisional designation 2001 DA42) is a Nysian asteroid from the inner regions of the asteroid belt, approximately 2.4 kilometers in diameter. It was discovered on 19 February 2001, by astronomers of the Lincoln Near-Earth Asteroid Research at the Lincoln Laboratory's Experimental Test Site in New Mexico, United States. The asteroid was named for novelist Douglas Adams.
208 Lacrimosa is a main-belt asteroid that was discovered by Austrian astronomer Johann Palisa on October 21, 1879, in Pola. The name derives from Our Lady of Sorrows, a title given to Mary, the mother of Jesus. It is orbiting the Sun at a distance of 2.89320 AU with a period of 4.92 yr and an eccentricity (ovalness) of 0.013. The orbital plane is inclined at an angle of 1.7° to the plane of the ecliptic.
230 Athamantis is a fairly large main-belt asteroid that was discovered by the German-Austrian astronomer K. de Ball on September 3, 1882, in Bothkamp. It was his only asteroid discovery. The asteroid was named after Athamantis, daughter of Athamas the mythical Greek king of Orchomenus.
238 Hypatia is a large main-belt asteroid that was discovered by Russian astronomer Viktor Knorre on July 1, 1884, in Berlin. It was the third of his four asteroid discoveries. The name was given in honour of philosopher Hypatia of Alexandria. Based upon the spectrum, it is classified as a C-type asteroid and is probably composed of primitive carbonaceous material. Like many asteroids of this type, its surface is very dark in colour.
334 Chicago is a very large main-belt asteroid. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
350 Ornamenta is a relatively large main-belt asteroid, measuring 118 km in diameter. It is classified as a C-type asteroid and is probably composed of carbonaceous material.
386 Siegena is a very large main-belt asteroid. It is classified as a C-type asteroid and is probably composed of primitive carbonaceous material.
556 Phyllis is a minor planet orbiting the Sun. It is an S-type asteroid with a diameter of 38 km and a geometric albedo of 0.185. Based on photometric observations between 1998 and 2006, it has a synodic rotation period of 4.293 ± 0.001 hours. The asteroid is named after Phyllis, a character in Greek mythology.
757 Portlandia is a main-belt asteroid 32 km in diameter. It was discovered on 30 September 1908 from Taunton, Massachusetts by the amateur American astronomer Joel E. Metcalf. The asteroid was named for the city of Portland, Maine, where Hastings was a church minister at the time. In November 2015, amateur astronomers captured it with images of comet 67P/Churyumov–Gerasimenko. Portlandia came to opposition in March 2016 at apparent magnitude 13.2.
796 Sarita is a minor planet orbiting the Sun. It was discovered 15 October 1914 by German astronomer Karl W. Reinmuth. This is a main belt that is orbiting at a radius of 2.63 AU with a period of 4.28 yr and an eccentricity (ovalness) of 0.32. The orbital plane is inclined at an angle of 19.052° from the plane of the ecliptic. Tholen (1989) initially classified it as type XD, although later authors treated it as an M-class body. The object's visual albedo is considered characteristic of the latter type. It has a significantly higher radar albedo than most main belt objects, which also suggests a higher metallic content.
1181 Lilith is a metallic asteroid from the middle region of the asteroid belt, approximately 23 kilometers in diameter. It was discovered on 11 February 1927, by Russian–French astronomer Benjamin Jekhowsky at Algiers Observatory in Algeria, Northern Africa, and named after French composer Lili Boulanger.
51825 Davidbrown (provisional designation 2001 OQ33) is an Eoan asteroid in the outer region of the asteroid belt, approximately 5 kilometers in diameter. It was discovered on 19 July 2001, by astronomers of the Near-Earth Asteroid Tracking program at Palomar Observatory in California, United States. The asteroid was named for American astronaut David Brown, who died in the Space Shuttle Columbia disaster.
51823 Rickhusband (provisional designation 2001 OY28) is a dark Lixiaohua asteroid from the outer regions of the asteroid belt, approximately 9 kilometers in diameter.
151997 Bauhinia, provisional designation 2004 JL1, is a sub-kilometer background asteroid from the inner regions of the asteroid belt, approximately 900 meters in diameter. It was discovered on 11 May 2004, by Canadian astronomer William Yeung at the Desert Eagle Observatory, Arizona, United States. It was named after the flowering plant Bauhinia blakeana also known as the "Hong Kong Orchid Tree".
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.
37432 Piszkéstető (provisional designation 2002 AE11) is an Erigonian asteroid from the inner regions of the asteroid belt, approximately 4.6 kilometers (2.9 miles) in diameter. It was discovered on 11 January 2002, by the Hungarian astronomers Krisztián Sárneczky and Zsuzsanna Heiner at the Konkoly Observatory's Piszkéstető Station northeast of Budapest, Hungary. The asteroid was later named for the discovering observatory.
185638 Erwinschwab (provisional designation 2008 EU7) is a potentially sub-kilometer Nysian asteroid from the inner regions of the asteroid belt. It was discovered on 1 March 2008, by OAM-astronomers at the La Sagra Observatory in southern Spain. The asteroid is estimated to measure between 950 meters and 1.8 kilometers in diameter and was named after German astronomer Erwin Schwab in 2009.
