148 Gallia (as Greek Γαλλία) is a large main-belt asteroid that is named after the Latin name for France: Gaul. Gallia was discovered by the French brothers Paul Henry and Prosper Henry on August 7, 1875, but the credit for this discovery was given to Prosper.[6] Based upon its spectrum, this is a GU-type asteroid in the Tholen classification taxonomy, while Bus and Binzel (2002) categorize it as an S-type asteroid.[4]
Photometric observations of this asteroid at the European Southern Observatory in 1977–78 gave a light curve with a period of 0.86098 ± 0.00030 days (20.6635 ± 0.0072 h) and a brightness variation of 0.32 in magnitude.[3] A 2007 study at the Palmer Divide Observatory in Colorado Springs, Colorado yielded a period of 20.666 ± 0.002 h with a magnitude variation of 0.21.[5]
This object is the namesake of a family of 22–113 asteroids that share similar spectral properties and orbital elements. Hence they may have arisen from the same collisional event. All members have a relatively high orbital inclination.[7]
