Asteroids named after people called Johan

(5274) Degewij

Named in honor of Johan Degewij (b. 1944), of Utrecht Polytechnic Institute, for his contributions to small-bodies research. Degewij was among the first to use spectroscopy to search for cometary activity on near-Earth asteroids and to detect color and polarization variations with rotation. His discovery of rotational albedo variegation on Vesta was the crucial observation that led to the recognition of its true rotation period as 5.34 hours, rather than 10.68 hours, the value accepted at the time. Degewij has also made significant contributions to the photometric study of comets, distant asteroids and the small satellites of Jupiter and Saturn. Name suggested and citation provided by E. F. Tedesco.Discovered 14 September 1985 by E. Bowell, Anderson Mesa

(5494) Johanmohr

German-Dutch astronomer Johan Maurits Mohr (1716-1775) made several successful meteorological and astronomical observations from his private observatory on the Molenvliet, Batavia, Dutch East Indies. The observations included some of the transits of Venus in 1761 and 1769.Discovered 19 October 1933 by K. Reinmuth, Heidelberg

(7857) Lagerros

Named in honor of Johan S. V. Lagerros (b. 1968) to celebrate the completion of his Ph.D. thesis titled “Thermal Physics of Asteroids”. In a series of papers, he extended and improved the Standard Thermal Model of minor planets. As a result, his model was used for the official calibration of ISO data. The discoverer has also benefited from his experience with computers on numerous occasions.Discovered 22 August 1978 by C.-I. Lagerkvist, Mount Stromlo

(9693) Bleeker

Johan Bleeker (b. 1942), director of the Durch Space Research Organization and professor of space physics at Utrecht University, wrote many papers on x-ray astrophysics. The codiscoverer of the diffuse x-ray background of the sky, he was also the first author of discovery papers on the primary electrons in cosmic rays.Discovered 24 September 1960 by van Houten, C. J., van Houten-Groeneveld, I., Gehrels, T., Palomar

(9911) Quantz

Johan Joachim Quantz (1697-1773), the son of a smith, became citypiper of Merseburg, Germany, and later came to the court in Dresden as an oboe player. Thirty years later he took up the flute, studying throughout Europe and introducing new techniques for the flute. In 1741 he became the teacher and musical conductor for the Prussian king Friedrich II the Great. Quantz composed about 500 pieces for flute and published a book about playing the flute and on Baroque music in general.Discovered 29 September 1973 by van Houten, C. J., van Houten-Groeneveld, I., Gehrels, T., Palomar

(11797) Warell

Johan Warell (b. 1970) is well known for his high-resolution imaging and spectroscopy of the planet Mercury with the Swedish solar telescope and the Nordic optical telescope on La Palma.Discovered 16 March 1980 by C.-I. Lagerkvist, La Silla

(11846) Verminnen

Johan Verminnen (b. 1951) is a Flemish artist, well known for his song Rue des Bouchers, named after a street in Brussels. This city is often the inspiration source for his songs, in Flemish and French, but also in the Brussels' dialect. Since 2007 he has been director of Sabam, the organization for the rights of artists.Discovered 21 September 1987 by E. W. Elst, Smolyan

(12857) Johandemessie

Johan DeMessie (b. 2005) was a finalist in the 2019 Broadcom MASTERS, a math and science competition for middle-school students, for his environmental and earth sciences project. He attended the Mason Middle School, Mason, Ohio.Discovered 21 April 1998 by LINEAR, Socorro

(13350) Gmelin

Johan Georg Gmelin (1709-1755) was a German naturalist who was appointed professor of chemistry and natural history at the University of St. Petersburg in 1731. From 1733 to 1743 he traveled through Siberia and his investigations were recorded in Flora Sibiria (1749-1750) and Reise durch Sibirien (1753).Discovered 20 September 1998 by E. W. Elst, La Silla

(24503) Kero

Johan Kero (b. 1978) is a scientist at the Swedish Institute of Space Physics whose research includes the radar detection of meteors. By studying meteor stream rates and radiant directions, his work contributes toward identifying their asteroid and comet sources.Discovered 3 January 2001 by LONEOS, Anderson Mesa

(25108) Bostrom

Johan Ingemar Boström (b. 1989) was awarded second place in the 2008 Intel International Science and Engineering Fair for his animal sciences team project. He attends the Donnergymnasiet Gothenburg, Gothenburg, Sweden.Discovered 14 September 1998 by LINEAR, Socorro

(79410) Wallerius

Swedish chemist and mineralogist Johan Gottschalk Wallerius (1709-1785) was the first holder (from 1750) of a professorship in chemistry, medicine and pharmacy at Uppsala University. He is considered the founder of agricultural chemistry. In 1761 he published his main work, Agriculturae fundamenta chemica.Discovered 3 May 1997 by E. W. Elst, La Silla

(483637) Johanstein

Johan Stein SJ (1888–1952) was a Dutch astronomer, a student of H. A. Lorentz, noted for his work on variable stars. He served as director of the Vatican Observatory from 1930 until his death. During the war he opened the observatory to 12,000 refugees. Queen Juliana made him a Knight of the Lion of Holland, and a lunar crater is named for him.Discovered 12 October 2004 by J. Zdanavičius K. Černis, Moletai
