678 Fredegundis
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. This object is orbiting at a distance of  with a period of  and an eccentricity (ovalness) of 0.22. The orbital plane is inclined at an angle of 6.1° to the plane of the ecliptic

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. References
