1341 Edmée
1341 Edmée, provisional designation, is a rare-type metallic asteroid from the central region of the asteroid belt, approximately 27 kilometers in diameter.
It was discovered on 27 January 1935, by Belgian astronomer Eugène Joseph Delporte at Uccle Observatory in Belgium, and later named after French astronomer Édmée Chandon.
Orbit and classification
Edmée orbits the Sun in the middle main-belt at a distance of 2.5–3.0 AU once every 4 years and 6 months. Its orbit has an eccentricity of 0.08 and an inclination of 13° with respect to the ecliptic. In 1917 it was first identified as at Heidelberg Observatory. The body's observation arc begins at Uccle, on the night following its official discovery observation in 1935.Physical characteristics
Edmée is classified as a rare XB-type in the Tholen taxonomy, an intermediary between the X and B type asteroids.Rotation period
American astronomer Robert Stephens obtained several rotational lightcurves of Edmée between 2004 and 2014. Best rated results include an observation taken at the Goat Mountain Research Observatory during the body's 2009-opposition, which gave a rotation period of 23.745 hours with a brightness variation of 0.05 magnitude, superseding an alternative period solution of 11.89.Because Edmées rotation is similar to that of Earth, photometric observations are challenging. In 2013, a much shorter period was derived from a fragmentary lightcurve at the Palomar Transient Factory in California.
