660 Crescentia is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on January 8, 1908. The name may have been inspired by the asteroid's provisional designation 1908 CC. Peter Ting points out that the Rev. Joel Metcalf of Taunton (Massachusetts) discovered six asteroids with unexplained names, though listed in Lutz Schmadel's book. Ting used an on-line planetarium website to help with the location of some of the planets, playing back to the night of discovery. He noticed that there was a crescent moon (33%) low in the western sky and wonders if the Rev. Metcalf could have named the asteroid for the Moon. Crescentia would be a very unusual name for a person but not for a phase of the Moon.
Crescentia is a member of the dynamic Maria family of asteroids that most likely formed as the result of a collisional breakup of a parent body. [2]
Maria is a Main belt asteroid that was discovered by French astronomer Henri Joseph Perrotin on January 10, 1877. Its orbit was computed by Antonio Abetti, and the asteroid was named after his sister, Maria. This is the namesake of the Maria asteroid family; one of the first asteroid families to be identified by Japanese astronomer Kiyotsugu Hirayama in 1918.
Roma is an asteroid. It was discovered by Luigi Carnera on July 11, 1901. Its provisional name was 1901 GP. This asteroid was named by Antonio Abetti for the city of Rome in Italy, the native country of its discoverer.
Adelaide is an S-type asteroid belonging to the Flora family in the Main Belt. It was discovered 21 October 1908 by Joel Hastings Metcalf.
Recha is a minor planet, specifically an asteroid orbiting in the asteroid belt between Mars and Jupiter. The asteroid, discovered by German astronomer Max Wolf on September 19, 1905, was named after a character in Gotthold Ephraim Lessing's play Nathan the Wise and may have been inspired by the asteroid's provisional designation 1905 RC.
Renate is a minor planet, specifically an asteroid orbiting in the asteroid belt which was discovered by German astronomer Max Wolf on September 19, 1905. The name may have been inspired by the asteroid's provisional designation 1905 RE.
Happelia is a minor planet orbiting the Sun. On 24 February 2017 a possible small 3-kilometer moon was found orbiting the asteroid, based on occultation observations.
611 Valeria is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on September 24, 1906, from Taunton, Massachusetts. The name may have been inspired by the asteroid's provisional designation 1906 VL.
616 Elly is a minor planet orbiting the Sun. It is a member of the Maria family of asteroids.
620 Drakonia is a minor planet, specifically an asteroid orbiting in the asteroid belt. It was discovered October 26, 1906, in Taunton, Massachusetts, by American astronomer Joel Hastings Metcalf and given the preliminary designation 1906 WE. It may have been named for Drake University.
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.
653 Berenike is a main-belt asteroid discovered on 27 November 1907 by Joel Hastings Metcalf at Taunton, Massachusetts. It is named after Berenice II of Egypt, after whom the constellation Coma Berenices is also named. The name may have been inspired by the asteroid's provisional designation 1907 BK.
661 Cloelia is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on February 22, 1908.
663 Gerlinde is a minor planet orbiting the Sun.
691 Lehigh is a minor planet orbiting the Sun, discovered in 1909. It is named "Lehigh" after Lehigh University, where its orbit was calculated in the Masters Thesis of Joseph B. Reynolds, following the observations of amateur astronomer Joel Metcalf.
696 Leonora is a Meliboean asteroid orbiting the Sun in the asteroid belt. It was discovered 10 January 1910 by American astronomer Joel Hastings Metcalf, at Taunton, Massachusetts. It was named by Arthur Snow of the United States Naval Observatory, who computed the orbit for the planet, after his wife, Mary Leonora Snow.
742 Edisona is a minor planet, specifically an asteroid orbiting in the asteroid belt that was discovered by German astronomer Franz Kaiser on February 23, 1913. It was named for inventor Thomas Edison. This asteroid is orbiting 3.01 AU with a period of 5.22 years and an eccentricity of 0.119. The orbital plane is inclined at an angle of 11.2° to the plane of the ecliptic. This is a member of the dynamic Eos family of asteroids that most likely formed as the result of a collisional breakup of a parent body.
755 Quintilla is a metallic background asteroid from the outer regions of the asteroid belt, approximately 36 kilometers in diameter. It was discovered on 6 April 1908, by American astronomer Joel Metcalf at the Taunton Observatory in Massachusetts, United States. For its size, the M-type asteroid has a relatively short rotation period of 4.55 hours. It was named Quintilla, an Italian female first name, for no reason other than being the first asteroid name beginning with the letter "Q".
756 Lilliana is a minor planet orbiting the Sun that was discovered by American astronomer Joel Hastings Metcalf on 26 April 1908 from Taunton, Massachusetts. It rotates around its axis of rotation every 9.36 hours.
875 Nymphe is a minor planet orbiting the Sun. It is a member of the Maria family of asteroids.
962 Aslög is a minor planet orbiting the Sun that was discovered by German astronomer Karl Wilhelm Reinmuth on 25 October 1921. Measurements of the lightcurve made in 2010 and 2011 give a rotation period of 5.465 ± 0.01 hours. It has a diameter of 39.5 km (24.5 mi).
