1154 Astronomia , provisional designation 1927 CB , is a carbonaceous background asteroid from the outer regions of the asteroid belt , approximately 60 kilometers in diameter. It was discovered by German astronomer Karl Reinmuth at the Heidelberg-Königstuhl State Observatory on 8 February 1927.[14] astronomy .
Orbit and classification [ edit ]
Astronomia is a background asteroid , that is, not a member of any known asteroid family .[4] outer main-belt at a distance of 3.2–3.6 AU eccentricity of 0.07 and an inclination of 5° with respect to the ecliptic .[1]
The asteroid was first identified as A911 RA at Heidelberg in September 1911. The body's observation arc begins the night after its official discovery observation at Heidelberg.[14]
Physical characteristics [ edit ]
In the Tholen classification , Astronomia has an ambiguous spectral type , closest to a carbonaceous F-type and somewhat similar to that of an X-type asteroid . Its spectrum has also been flagged as unusual and of poor quality (FXU:).[1]
Rotation period [ edit ]
In May 2016, the first rotational lightcurve of Astronomia was obtained from photometric observations. Lightcurve analysis gave a rotation period of 18.1154 hours with a brightness variation of 0.39 magnitude (U=3- [a]
Diameter and albedo [ edit ]
According to the surveys carried out by the Infrared Astronomical Satellite IRAS , the Japanese Akari satellite and the NEOWISE mission of NASA's Wide-field Infrared Survey Explorer , Astronomia measures between 55.4 and 64.20 kilometers in diameter and its surface has an albedo between 0.028 and 0.04.[5] [6] [7] [8] [9] [10] [12]
The Collaborative Asteroid Lightcurve Link adopts the results obtained by IRAS, that is an albedo of 0.0296 and a diameter of 61.08 kilometers based on an absolute magnitude of 10.51.[3] [11]
This minor planet was named after the natural science of astronomy , a study of celestial objects , observations and phenomena in the night sky . The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 108 [2]
