413 Edburga
Edburga (minor planet designation: 413 Edburga) is a typical Main belt asteroid. Max Wolf discovered it on 7 January 1896 at Heidelberg Observatory. The origin of the name is unknown. This asteroid is orbiting the Sun at a distance of  with a period of  and an eccentricity of 0.34. Its orbital plane is inclined at an angle of 18.7° to the plane of the ecliptic. Analysis of the asteroid's light curve based on photometric data collected during 2011 shows a rotation period of  with a brightness variation of  in magnitude. This is consistent with prior results. This is classified as an M-type asteroid in the Tholen system and X-type in the Bus and Binzel taxonomy, with a moderate albedo and generally featureless near infrared spectra. An absorption feature has been detected at a wavelength 3 μm, suggesting this is W-type. It spans a diameter of . Radar echoes are bimodal, suggesting a bifurcated structure that is likely a contact binary. References
