1294 Antwerpia (

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

Antwerpia is a non-

Heidelberg Observatory in February 2017, where the body's observation arc begins one month later in March 2017.[3]

Naming

Physical characteristics

In the

Small Solar System Objects Spectroscopic Survey (S3OS2).[5][13]

Rotation period and poles

Several rotational

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

According to the surveys carried out by the Infrared Astronomical Satellite

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]
