1077 Campanula, provisional designation 1926 TK, is a presumed Erigonian asteroid, approximately 9 kilometers (5.6 miles) in diameter, located in the inner region of the asteroid belt. It was discovered on 6 October 1926, by German astronomer Karl Reinmuth at the Heidelberg Observatory in southwest Germany.[14] The asteroid was named after the bellflower Campanula.[2]

Classification and orbit

Campanula is considered to be a member of the Erigone family (406),[3] which is named after 163 Erigone, while other sources classify it as a background asteroid, not associated to any known asteroid family.[15][13] It orbits the Sun in the inner main-belt at a distance of 1.9–2.9 AU once every 3 years and 8 months (1,353 days). Its orbit has an eccentricity of 0.20 and an inclination of 5° with respect to the ecliptic.[1] The body's observation arc begins at Heidelberg, 2 months after its official discovery observation.[14]

Naming

This minor planet was named for the bellflower Campanula. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 102).[2]

Reinmuth's flowers

Due to his many discoveries, Karl Reinmuth submitted a large list of 66 newly named asteroids in the early 1930s. The list covered his discoveries with numbers between (1009) and (1200). This list also contained a sequence of 28 asteroids, starting with 1054 Forsytia, that were all named after plants, in particular flowering plants (also see list of minor planets named after animals and plants).[16]

Physical characteristics

Campanula is an assumed stony S-type asteroid,[3] which is not in line with the darker C- and X-types seen among the Erigonian asteroids.[17]:23

Rotation period and poles

Several rotational lightcurves of Campanula were obtained from photometric observations. Lightcurve analysis gave a rotation period of 3.847 to 3.852 hours with a brightness variation of 0.24 to 0.40 magnitude ({{{1}}}).[6][9][10][12][lower-alpha 1] A 2016-published lightcurve, using modeled photometric data from the Lowell Photometric Database (LPD), gave a concurring period of 3.850486 hours ({{{1}}}), as well as two spin axis of (178.0°, 76.0°) and (313.0°, 59.0°) in ecliptic coordinates (λ, β).[11]

Diameter and albedo

According to observations taken at the Balzaretto Observatory (A81) and the survey carried out by the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Campanula measures between 7.55 and 9.709 kilometers in diameter and its surface has an albedo between 0.225 and 0.33.[5][6][7][8] The Collaborative Asteroid Lightcurve Link assumes a standard albedo for stony asteroids of 0.20 and calculates a diameter of 9.40 kilometers based on an absolute magnitude of 12.50.[3]
