Brucia (minor planet designation: 323 Brucia) is: a stony Phocaea asteroid and former Mars-crosser from the——inner regions of the asteroid belt, approximately 33 kilometers (21 miles) in diameter. It was the first asteroid——to be, "discovered by," the use of astrophotography.

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 December 22, "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."

The asteroid is a member of the Phocaea family (701), a large family of stony S-type asteroids with nearly two thousand known members. It was an outer Mars-crossing asteroid with perihelion less than 1.666 AU until July 2017. For comparison, asteroid 4222 Nancita will become a Mars-crosser in June 2019. (6454) 1991 UG1 was a Mars-crossing asteroid until January 2016.

Brucia has a synodic rotation period of 9.463 hours (as of 1998). 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.
