Template:Short description Template:Use dmy dates Template:Infobox planet
148 Gallia is an asteroid from the central regions of the asteroid belt, approximately Template:Convert in diameter. It was discovered on 7 August 1875, by the French brothers Paul Henry and Prosper Henry at the Paris, but the credit for this discovery was given to Prosper.<ref name="MPC-object" /> It was named after the Latin name for the country of France, Gaul.<ref name="springer" /> Based upon its spectrum, it is an unusual G-type asteroid (GU) and a stony S-type asteroid in the Tholen and SMASS classification, respectively.<ref name="jpldata" /><ref name="Lazzaro-2004" />
Photometric observations of this asteroid at the European Southern Observatory in 1977–78 gave a light curve with a period of Template:Convert and a brightness variation of 0.32 in magnitude.<ref name="Surdej-1979" /> A 2007 study at the Palmer Divide Observatory in Colorado, United States, yielded a period of 20.666 ± 0.002 hours with a magnitude variation of 0.21.<ref name="Warner-2007h" />Template:Efn
This object is the namesake of the Gallia family (Template:Small), a small family of nearly 200 known stony asteroids that share similar spectral properties and orbital elements.<ref name="Nesvorny-2014" /> Hence they may have arisen from the same collisional event. All members have a relatively high orbital inclination.<ref name="Novakovic-2011" />
