1294 Antwerpia

December 02, 2023

1294 Antwerpia (prov. designation: 1933 UB1) is a dark background asteroid from the central regions of the asteroid belt. It was discovered on 24 October 1933, by astronomer Eugène Delporte at the Royal Observatory of Belgium in Uccle.[3] The carbonaceous C-type asteroid has a rotation period of 6.6 hours and measures approximately 35 kilometers (22 miles) in diameter. It was named for the Belgian city of Antwerp.[2]

Orbit and classification edit

Antwerpia is a non-family asteroid of the main belt's background population when applying the hierarchical clustering method to its proper orbital elements.[4][5] It orbits the Sun in the central main belt at a distance of 2.1–3.3 AU once every 4 years and 5 months (1,608 days). Its orbit has an eccentricity of 0.23 and an inclination of 9° with respect to the ecliptic.[1] the asteroid was first observed as A917 DB at Heidelberg Observatory in February 2017, where the body's observation arc begins one month later in March 1917.[3]

Naming edit

This minor planet was named after the city of Antwerp in Flanders, the Dutch-speaking part of Belgium. The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 118).[2]

Physical characteristics edit

In the SMASS classification, Antwerpia is a carbonaceous C-type asteroid.[1] It is also a C-type in both the Tholen- and SMASS-like taxonomy of the Small Solar System Objects Spectroscopic Survey (S3OS2).[5][13]

Rotation period and poles edit

Several rotational lightcurves of Antwerpia have been obtained from photometric observations since 2005. Lightcurve analysis gave a rotation period of 6.63 hours with a brightness variation of 0.42 magnitude (U=1/3/3-/3-/3/2).[15][16][17][14][18][12][a]

A 2016-published lightcurve, using modeled photometric data from the Lowell Photometric Database (LPD), gave a concurring period of 6.62521 hours (U=n.a.), as well as two spin axis of (128.0°, −66.0°) and (246.0°, −76.0°) in ecliptic coordinates (λ, β).[19]

Diameter and albedo edit

According to the surveys carried out by the Infrared Astronomical Satellite IRAS, the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer, Antwerpia measures between 27.82 and 40.717 kilometers in diameter and its surface has an albedo between 0.0887 and 0.125.[6][7][8][9][10] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0783 and a diameter of 34.40 kilometers based on an absolute magnitude of 10.7.[11]
