67 Asia is a largemain beltasteroid. It was discovered by English astronomerN. R. Pogson on April 17, 1861, from theMadras Observatory. Pogson chose the name to refer both toAsia, a figure inGreek mythology, and to thecontinent of Asia, because the asteroid was the first to be discovered from that continent.[4]

This object is orbiting theSun with aperiod of 3.77 years, asemimajor axis of2.421 AU, and aneccentricity of 0.185. It has a 2:1commensurability withMars, having an orbital period double that of the planet.[5] Theorbital plane lies at an inclination of 6.0° to theplane of the ecliptic. This is a stonyS-type asteroid with a cross-sectional size of 61 km,[2]Photometry from the Oakley Observatory during 2006 produced alightcurve that indicated asidereal rotation period of15.90±0.02 with anamplitude of0.26±0.04 in magnitude.[6]
