678 Fredegundis is a minor planet orbiting the Sun. It was discovered 22 January 1909 from Heidelberg by German astronomer K. Wilhelm Lorenz, and was named after the French opera Frédégonde.[1] This object is orbiting at a distance of Script error: No such module "val". with a period of Script error: No such module "convert". and an eccentricity (ovalness) of 0.22. The orbital plane is inclined at an angle of 6.1° to the plane of the ecliptic[2]
This appears to be an M-type asteroid in the Tholen classification and X-type in the Bus and Binzel system. It spans a girth of approximately 42 km and is spinning with a rotation period of 11.6201 hours. Radar observations suggest a bifurcated structure consistent with a contact binary.[3]
