1275 Cimbria (

Karl Reinmuth at the Heidelberg-Königstuhl State Observatory in southern Germany.[16] The asteroid was named after the Cimbri, an ancient Germanic tribe.[3]

Orbit and classification

Cimbria is a member of the

502),[4][5] a prominent family of typically stony asteroids and the largest one in the intermediate main belt with more than 5,000 members.[17]

The asteroid orbits the Sun in the central main-belt at a distance of 2.2–3.1 AU once every 4 years and 5 months (1,603 days). Its orbit has an eccentricity of 0.17 and an inclination of 13° with respect to the ecliptic.[1] It was first identified as A914 TG at Simeiz Observatory in October 1914. The body's observation arc begins with its official discovery observation at Heidelberg in 1932.[16]

Physical characteristics

In the

Tholen classification, Cimbria is an X-type asteroid, rather than a stony S-type asteroid, which is the overall spectral type for members of the Eunomia family.[17]

Poles

The asteroid's lightcurve has also been modeled using photometric data from the Lowell Photometric Database. It gave a concurring period of 5.65454 hours and determined two spin axis of (85.0°, −61.0°) and (271.0°, −31.0°) in ecliptic coordinates (λ, β).[13]

Diameter and albedo

According to the surveys carried out by the Infrared Astronomical Satellite

albedo between 0.0807 and 0.25.[6][7][8][9][10][11]

The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is an albedo of 0.1109 and a diameter of 28.65 kilometers based on an absolute magnitude of 10.72.[4][9]
