Ada (minor planet designation: 523 Ada) is a minor planet orbiting the Sun. It was discovered January 29, 1904, by American astronomer Raymond S. Dugan at Heidelberg, Germany and was named after his friend Ada Helme. CCD images collected during the fall of 2004 at Oakley Observatory in Terre Haute, Indiana, were used to generate a lightcurve for the object, showing a rotation period of 10.03 ± 0.01 hours. [2]
Bellona is a large main-belt asteroid. It was discovered by German astronomer R. Luther on March 1, 1854, and named after Bellōna, the Roman goddess of war; the name was chosen to mark the beginning of the Crimean War. It is a stony (S-type) asteroid with a cross-section size of around 100–120 km. 28 Bellona is orbiting the Sun with a period of 4.63 years.
Prymno is a somewhat large Main belt asteroid. It is classified as a B-type asteroid and probably has a primitive composition not unlike common C-type carbonaceous asteroids.
Ducrosa is a typical Main belt asteroid. It was discovered by Auguste Charlois on 15 March 1895 in Nice.
Caprera is a minor planet orbiting the Sun.
Virtus is an 86 km minor planet orbiting the Sun. It was discovered by Max Wolf on October 7, 1902. Its provisional name was 1902 JV.
Laodica is a minor planet orbiting the Sun.
Brixia is a relatively large minor planet, specifically an asteroid orbiting mostly in the asteroid belt that was discovered by American astronomer Raymond Smith Dugan on January 10, 1904. The name derives from Brixia, the ancient name of the Italian city of Brescia.
Fidelio is a large minor planet with a diameter of 71 km, orbiting the Sun near the center of the main asteroid belt. Fidelio contains both metals and carbon. Concerning its name, the Catalogue of Minor Planet Names and Discovery Circumstances notes, "This is the name of Leonora when disguised as a man in the opera Fidelio by the German composer Ludwig van Beethoven. The name dates from a period when Max Wolf assigned the names of female operatic characters to asteroids he had newly discovered.
Montague is a minor planet orbiting the Sun that was discovered by Raymond Smith Dugan on 7 May 1904 in Heidelberg, Germany. It was named after the town Montague in Massachusetts.
Merapi is a main belt asteroid orbiting the Sun. It was discovered by American astronomer George Henry Peters on May 11, 1904, from Washington, D.C.
Pamina is a minor planet orbiting the Sun in the main belt. It is named for the heroine of Mozart's opera, The Magic Flute. This asteroid was discovered by M. Wolf in 1904 at the Heidelberg observatory in Germany. It is orbiting at a distance of 2.74 AU from the Sun, with an orbital eccentricity (ovalness) of 0.212 and a period of 4.53 yr. The orbital plane is inclined at an angle of 6.8° to the ecliptic.
Herodias is a carbonaceous asteroid from the central regions of the asteroid belt, approximately 66 kilometers in diameter. It is an identified Eunomian interloper. It was named after the biblical character Herodias.
Jessonda is a minor planet orbiting the Sun. According to the Catalogue of Minor Planet Names and Discovery Circumstances, it is "named presumably after the character in the opera of the same name by the German composer, conductor and violinist Ludwig Spohr (1784-1859), one of the leading composers in the early romantic period.'
616 Elly is a minor planet orbiting the Sun. It is a member of the Maria family of asteroids.
630 Euphemia is a mid-sized Eunomian asteroid.
633 Zelima is a minor planet orbiting the Sun in the asteroid belt with a magnitude of 10.7. The name may have been inspired by the asteroid's provisional designation 1907 ZM.
635 Vundtia is a minor planet orbiting the Sun - though this claim has been disputed.
883 Matterania is an S-type asteroid belonging to the Flora family in the Main Belt. Its rotation period is 5.64 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.
(523645) 2010 VK201, provisional designation 2010 VK201, is a trans-Neptunian object and member of the classical Kuiper belt, approximately 500 kilometers (310 miles) in diameter. It was discovered on 1 November 2010, by the Pan-STARRS 1 survey at Haleakala Observatory, Hawaii, United States. It has a rotation period of 7.6 hours. It was numbered in September 2018 and remains unnamed.
