Dark Nysian asteroid from the inner regions of the asteroid belt
1378 Leonce , provisional designation 1936 DB , is a dark Nysian asteroid from the inner regions of the asteroid belt , approximately 19 kilometers in diameter. It was discovered on 21 February 1936, by Belgian astronomer Fernand Rigaux at the Royal Observatory of Belgium in Uccle, who named it after his father, Leonce Rigaux.[2] [15]
Orbit and classification [ edit ]
Leonce is a member of the Nysa family (405 [4] asteroid families .[16] : 23
It orbits the Sun in the inner asteroid belt at a distance of 2.0–2.7 AU eccentricity of 0.15 and an inclination of 4° with respect to the ecliptic .[1]
The asteroid was first identified as 1915 RC at Heidelberg Observatory in September 1915. One week later, the body's observation arc begins at Bergedorf Observatory , more than 20 years prior to its official discovery observation at Uccle.[15]
Physical characteristics [ edit ]
Leonce is an assumed carbonaceous C-type asteroid .[3]
Rotation period and poles [ edit ]
In 2002, 2007 and 2017, three rotational light curves of Leonce were obtained from photometric observations by amateur astronomers René Roy , Laurent Bernasconi and Daniel Klinglesmith and colleagues at Etscorn Observatory (719 rotation period of 4.3250 hours and a brightness amplitude between 0.49 and 0.63 magnitude (U=3/3/3 [3] [11] [12]
In addition a modeled light curve, using photometric data from various sources, gave a period of 4.32527 hours, as well as two spin axes of (210.0°, −67.0°) and (46.0°, −77.0°) in ecliptic coordinates .[13]
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 , Leonce measures between 14.94 and 22.456 kilometers in diameter and its surface has an albedo between 0.0348 and 0.10.[5] [6] [7] [8] [9] [10]
The Collaborative Asteroid Lightcurve Link derives an albedo of 0.0706 and a diameter of 18.16 kilometers based on an absolute magnitude of 12.2.[3]
This minor planet was named after Leonce Rigaux, father of the discoverer astronomer Fernand Rigaux . The official naming citation was mentioned in The Names of the Minor Planets by Paul Herget in 1955 (H 125 [2]
