758 Mancunia is aminor planet orbiting theSun. It was discovered in 1912 from Johannesburg byH. E. Wood, aMancunian. This object is orbiting at a distance of3.19 AU with aperiod of 5.70 years and aneccentricity (ovalness) of 0.15. Theorbital plane is inclined at an angle of 5.61° to theplane of the ecliptic.[2]
Observation of this asteroid in 1996 suggested arotation period of 6.902 hours. However,radar observations fromArecibo indicated this may be in error. Independentphotometry measurements made during December 2006 were combined to determine an estimated period nearly double that of the original, or12.7253±0.0006 h with a brightness variation amplitude of0.26±0.02 in magnitude.[4] A high radar albedo indicates this object is most likely metallic. Dips in the radar echo suggests there are large concavities on both sides. It is classified as anX-type asteroid in theTholen taxonomy and spans a girth of85±7 km.[5]
