766 Moguntia
766 Moguntia is a minor planet orbiting the Sun. It was discovered on 29 September 1913 at Heidelberg by German astronomer Franz Kaiser, and is named after Mainz, ancient Moguntiacum. This object is a member of the same dynamic asteroid group as 221 Eos, the Eos family. It is orbiting at a distance of 3.02 AU from the Sun with a period of 5.24 years and an eccentricity (ovalness) of 0.097. The orbital plane is inclined at an angle of 10.1° to the plane of the ecliptic.
