From Wikipedia, the free encyclopedia
1276 Ucclia (
prov. designation : 1933 BA ) is a carbonaceous
Alauda asteroid from the outer region of the
asteroid belt , approximately 31 kilometers (19 miles) in diameter. It was discovered on 24 January 1933 by Belgian astronomer
Eugène Delporte at the
Royal Observatory of Belgium in Uccle.
[15] Two nights later, the body was independently discovered by
Richard Schorr at
Bergedorf Observatory in Hamburg, Germany. It was named for the Belgium city of
Uccle and its discovering observatory.
[2]
Orbit and classification
Ucclia is a member of the
Alauda family (
902 ),
[4] a large
family of typically bright carbonaceous asteroids named after its parent body,
702 Alauda .
[16] : 23 It orbits the Sun in the
outer main-belt at a distance of 2.9–3.5
AU once every 5 years and 8 months (2,069 days). Its orbit has an
eccentricity of 0.09 and an
inclination of 23
° with respect to the
ecliptic .
[1] No
precoveries were taken prior to its discovery.
[15]
Naming
This
minor planet was named after
Uccle , in honor of both, the city and the discovering observatory (
H 117 ).
[2]
Physical characteristics
Rotation period
A rotational
lightcurve of Ucclia was obtained from photometric observations by Italian and French astronomers
Silvano Casulli , Federico Manzini and
Pierre Antonini in March 2007. It showed a well-defined
rotation period of 4.90768 hours with a brightness variation of 0.40 in
magnitude (
U=3 ).
[13] In June 2008, a second light-curve by Slovak astronomer
Adrián Galád at
Modra Observatory , gave a concurring period of 4.9073 hours with an amplitude of 0.29 in magnitude (
U=3- ).
[11]
Diameter and albedo
According to the surveys carried out by the Infrared Astronomical Satellite
IRAS , the Japanese
Akari satellite, and NASA's
Wide-field Infrared Survey Explorer with its subsequent
NEOWISE mission, Ucclia measures between 30.1 and 40.0 kilometers in diameter and its surface has an
albedo between 0.05 and 0.14.
[5]
[6]
[7]
[9] The Collaborative Asteroid Lightcurve Link derives an albedo of 0.08 and a diameter of 30.3 kilometers.
