758 Mancunia is a minor planet orbiting the Sun. It was discovered in 1912 from Johannesburg by H. E. Wood, a Mancunian. This object is orbiting at a distance of 3.19 AU with a period of 5.70 years and an eccentricity (ovalness) of 0.15. The orbital plane is inclined at an angle of 5.61° to the plane of the ecliptic.[2]

Observation of this asteroid in 1996 suggested a rotation period of 6.902 hours. However, radar observations from Arecibo indicated this may be in error. Independent photometry measurements made during December 2006 were combined to determine an estimated period nearly double that of the original, or 12.7253±0.0006 h with a brightness variation amplitude of 0.26±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 an X-type asteroid in the Tholen taxonomy and spans a girth of 85±7 km.[5]
