    Dorothea (minor planet designation: 339 Dorothea) is a large main belt asteroid that was discovered by German astronomer Max Wolf on 25 September 1892 in Heidelberg.

    This is a member of the dynamic Eos family of asteroids that were probably formed as the result of a collisional breakup of a parent body. [3]

    This asteroid is named after astronomer Dorothea Klumpke, [4] as is 1040 Klumpkea.

    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.

    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.

    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.
