    2807 Karl Marx, provisional designation 1969 TH6, is a carbonaceous Dorian asteroid from the central region of the asteroid belt, approximately 17 kilometers in diameter. It was discovered on 15 October 1969, by Russian astronomer Lyudmila Chernykh at the Crimean Astrophysical Observatory in Nauchnyj on the Crimean peninsula. The asteroid was later named for the German philosopher Karl Marx.

    2598 Merlin, provisional designation 1980 RY, is a carbonaceous Dorian asteroid from the central regions of the asteroid belt, approximately 16 kilometers in diameter. It was discovered on 7 September 1980, by American astronomer Edward Bowell at Lowell's Anderson Mesa Station in Flagstaff, Arizona, United States. The asteroid was named after the legendary wizard Merlin in Arthurian legend.

    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.
