'''67 Asia''' is a large [[main belt]] [[asteroid]]. It was discovered by English astronomer [[Norman Robert Pogson|N. R. Pogson]] on April 17, 1861, from the [[Madras Observatory]]. Pogson chose the name to refer both to [[Asia (Greek myth)|Asia]], a figure in [[Greek mythology]], and to the [[Asia|continent of Asia]], because the asteroid was the first to be discovered from that continent.<ref name=Schmadel2003/>

This object is orbiting the [[Sun]] with a [[orbital period|period]] of {{Convert|1376.048|days|years|2|disp=out|abbr=off}}, a [[semimajor axis]] of {{Val|2.421|ul=AU}}, and an [[orbital eccentricity|eccentricity]] of 0.185. It has a 2:1 [[Commensurability (astronomy)|commensurability]] with [[Mars]], having an orbital period double that of the planet.<ref name="Platsino1992" /> The [[orbital plane]] lies at an inclination of 6.0° to the [[plane of the ecliptic]]. This is a stony [[S-type asteroid]] with a cross-sectional size of 61 km,<ref name="Carry2012" /> [[Photometry (astronomy)|Photometry]] from the Oakley Observatory during 2006 produced a [[lightcurve]] that indicated a [[sidereal rotation period]] of {{Val|15.90|0.02}} with an [[amplitude]] of {{Val|0.26|0.04}} in magnitude.<ref name="Ditteon2007" />
