1044 Teutonia, provisional designation1924 RO, is a stonyasteroid from the central regions of theasteroid belt, approximately 16 kilometers in diameter. It was discovered on 10 May 1924, by astronomerKarl Reinmuth atHeidelberg Observatory in southwest Germany.[13] The asteroid was named after the land inhabited by theTeutonic people.[2]
Teutonia orbits the Sun in thecentral main-belt at a distance of 2.2–2.9 AU once every 4 years and 2 months (1,510 days). Its orbit has aneccentricity of 0.14 and aninclination of 4° with respect to theecliptic.[1]
The asteroid'sobservation arc begin 17 years prior to its official discovery observation, with its first identification asA907 EE at Taunton Observatory (803) in March 1907.[13]
Images of the object made during 2007 were used to produce alight curve that gave a synodic period of 2.84 ± 0.04 h. However, a study made in 2006 gave a period of 3.153 ± 0.003, which can not yet be ruled out. The brightness of the object varied by 0.20 ± 0.03 inmagnitude over the course of each rotation.[8]
According to the surveys carried out by the Infrared Astronomical SatelliteIRAS, the JapaneseAkari satellite, and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Teutonia measures between 15.20 and 17.929 kilometers in diameter and its surface has analbedo between 0.2449 and 0.3340.[3][5][6][7] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.3613 and a diameter of 15.30 kilometers based on anabsolute magnitude of 10.8.[4]
Thisminor planet was named for the land once inhabited by theTeutons, a Germanic tribe that lived in what is nowJutland. The name was proposed by astronomer Gustav Stracke.[2]
