Arnold Schwassmann
Friedrich Karl Arnold Schwassmann (25 March 1870 – 19 January 1964) was a German astronomer and a discoverer of 22 minor planets and 4 comets, who worked at AOP in Potsdam and at Bergedorf Observatory in Hamburg. He was co-discoverer with Arno Arthur Wachmann of the periodic comets 29P/Schwassmann–Wachmann, 31P/Schwassmann–Wachmann and 73P/Schwassmann–Wachmann, and with Arno Arthur Wachmann and Leslie Peltier Leslie Copus Peltier (January 2, 1900 – May 10, 1980) was an American amateur astronomer and discoverer of several comets and novae, including Nova Herculis 1963. He was once described as "the world's greatest non-professional astronomer" by ... of the non-periodic comet C/1930 D1 (Peltier–Schwassmann–Wachmann). The main-belt asteroid 989 Schwassmannia, discovered by himself in 1922, was later named in his honor ().

Minor Planet
According to the International Astronomical Union (IAU), a minor planet is an astronomical object in direct orbit around the Sun that is exclusively classified as neither a planet nor a comet. Before 2006, the IAU officially used the term ''minor planet'', but that year's meeting reclassified minor planets and comets into dwarf planets and small Solar System bodies (SSSBs).Press release, IAU 2006 General Assembly: Result of the IAU Resolution votes International Astronomical Union, August 24, 2006.

912 Maritima
912 Maritima is an asteroid in the asteroid belt. Based on lightcurve studies observing Maritima over a three-month period, Maritima has a rotation period of 1332 hours. Analysis reveals a possible synodic period of . Superslow rotators, those with periods longer than a few days, are generally small asteroids. The current paradigm is that slowing of an asteroid's spin rate is the result of Yarkovsky–O'Keefe–Radzievskii–Paddack effect, YORP radiation pressure, which acts on the target as the inverse square of its size and the inverse of its semi-major axis. The rotation period is less than conclusive. References External links Lightcurve plot of 912 Maritima Palmer Divide Observatory, Brian D. Warner, B. D.

458 Hercynia
Hercynia (minor planet designation: 458 Hercynia), provisional designation , is a background asteroid from the outer regions of the asteroid belt, approximately 38 kilometers in diameter. It was discovered on 21 September 1900, by astronomers Max Wolf and Arnold Schwassmann at the Heidelberg-Königstuhl State Observatory in southwest Germany. The asteroid was named for the ancient Hercynian Forest, known to the Romans as "Hercynia silva". Orbit and classification ''Hercynia'' is a non-family asteroid of the main belt's background population.

457 Alleghenia
Alleghenia (minor planet designation: 457 Alleghenia), provisional designation 1900 FJ, is a carbonaceous asteroid from the outer region of the asteroid belt, about 34 kilometers in diameter. It was discovered on 15 September 1900, by German astronomers Max Wolf and Friedrich Schwassmann at Heidelberg Observatory in southern Germany.

Its orbit is tilted by 13 degrees to the plane of the ecliptic and shows an eccentricity of 0.17. Based on assumptions made by the ''Collaborative Asteroid Lightcurve Link'', the body has a low albedo of 0.06, a typical value for a carbonaceous asteroid. In 2014, photometric light-curve observations at the Los Algarrobos Observatory (OLASU, I38), Uruguay, has given a rotation period of hours with a brightness amplitude of 0.20 in magnitude.
