Template:Short description Template:Use dmy dates Template:Infobox planet
323 Brucia is a stony Phocaea asteroid and former Mars-crosser from the inner regions of the asteroid belt, approximately Template:Convert in diameter. It was the first asteroid to be discovered by the use of astrophotography.<ref name="Campbell-1892" />
Description
Brucia was also the first of over 200 asteroids discovered by Max Wolf, a pioneer in that method of finding astronomical objects. Discovered on 22 December 1891, when he was 28 years old, it was named in honour of Catherine Wolfe Bruce, a noted patroness of the science of astronomy, who had donated $10,000 for the construction of the telescope used by Wolf.<ref name="springer" /><ref name="MPC-object" />
The asteroid is a member of the Phocaea family (Template:Small),<ref name="Ferret" /> a large family of stony S-type asteroids with nearly two thousand known members.<ref name="Nesvorny-2014" />Template:Rp It was an outer Mars-crossing asteroid with perihelion less than 1.666 AU<ref name="jpldata" /> until July 2017. For comparison, asteroid 4222 Nancita will become a Mars-crosser in June 2019. Template:Mpl was a Mars-crossing asteroid until January 2016.<ref>Template:Cite web</ref>Template:Update after
Brucia has a synodic rotation period of 9.463 hours (as of 1998).<ref name="lcdb" /> According to the survey carried out by the Infrared Astronomical Satellite, Brucia measures 35.82 kilometers in diameter and its surface has an albedo of 0.1765.<ref name="SIMPS" />
