1353 Maartje, provisional designation 1935 CU, is an Eoan asteroid from the outer regions of the asteroid belt, approximately 37 kilometers in diameter. It was discovered on 13 February 1935, by Dutch astronomer Hendrik van Gent at the Union Observatory in Johannesburg, South Africa.[16] The asteroid was named after Maartje Mekking, daughter of a staff member at the Dutch Leiden Observatory.[2]

Orbit and classification

Maartje is a member the

semi-major axis of 3.01 AU). Its orbit has an eccentricity of 0.10 and an inclination of 9° with respect to the ecliptic.[1]

In June 1910, the asteroid was first identified as A910 LB at the

Heidelberg Observatory in Germany, where the body's observation arc begins with its identification as A920 JC in May 1920, almost 15 years prior to its official discovery observation at Johannesburg.[16]

U=3).[3] The asteroid's lightcurve has also been modeled and gave two concurring periods of 22.9924 and 22.9926 hours.[13][14][a] Modeling in 2018 determined two spin axis of (285.0°, 73.0°) and (119.0°, 41.0°) in ecliptic coordinates (λ, β).[13]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.0687 and 0.136.[5][6][7][8][9][10]

The Collaborative Asteroid Lightcurve Link derives an albedo of 0.1660 and a diameter of 34.16 kilometers based on an absolute magnitude of 9.9.[3]
