1466 Mündleria, provisional designation1938 KA, is a carbonaceousasteroid from the inner regions of theasteroid belt, approximately 22 kilometers in diameter.
It was discovered on 31 May 1938, by German astronomerKarl Reinmuth atHeidelberg Observatory in southern Germany, and later named after German astronomerMax Mündler.[2][9]
Mündleria orbits the Sun in theinner main-belt at a distance of 2.0–2.7 AU once every 3 years and 8 months (1,339 days). Its orbit has aneccentricity of 0.16 and aninclination of 13° with respect to theecliptic.[1]Mündleria'sobservation arc begins with its official discovery observation in 1938. It was first identified as1923 GA at Heidelberg in 1923.[9]
The asteroid has been characterized as a carbonaceousC-type asteroid.[3]
According to the surveys carried out by the JapaneseAkari satellite and NASA'sWide-field Infrared Survey Explorer with its subsequentNEOWISE mission,Mündleria measures between 22.13 and 24.95 kilometers in diameter, and its surface has analbedo between 0.037 and 0.061.[4][5][6][7] TheCollaborative Asteroid Lightcurve Link derives an albedo of 0.055 and a diameter of 21.46 kilometers with anabsolute magnitude of 12.1.[3]
Photometric observations of asteroid 1466 Mundleria (e = 0.15, i = 13.15°, H = 12.23) were conducted using telescopes located in New Mexico, Italy, and Malta between March 24th and April 25th, 2022. An analysis of these data points yielded a rotation period of 89.28 ± 0.065 hours.[10]
Thisminor planet was named after German astronomer Max Mündler (1876–1969), staff member at the Heidelberg-Königstuhl State Observatory where the body was discovered. The name was proposed byHeinrich Vogt after whom the minor planet1439 Vogtia is named. The official naming citation was mentioned inThe Names of the Minor Planets byPaul Herget in 1955 (H 131).[2]
