Edburga (minor planet designation: 413 Edburga) is a typical Main belt asteroid. Max Wolf discovered it on 7 January 1896 at Heidelberg Observatory.[1] The origin of the name is unknown.[3] This asteroid is orbiting the Sun at a distance of 2.58 astronomical unit|AU with a period of 4.15 yr and an eccentricity of 0.34. Its orbital plane is inclined at an angle of 18.7° to the plane of the ecliptic.[1]
Analysis of the asteroid's light curve based on photometric data collected during 2011 shows a rotation period of 15.78±0.02 h with a brightness variation of 0.53±0.02 in magnitude. This is consistent with prior results.[4] This is classified as an M-type asteroid in the Tholen system and X-type in the Bus and Binzel taxonomy,[5] 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.[5] It spans a diameter of 31.95±2.8 km.[6] Radar echoes are bimodal, suggesting a bifurcated structure that is likely a contact binary.[5]
