323 Brucia

Phocaea asteroid

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.[14]

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.[2][15]

The asteroid is a member of the Phocaea family (701),[3] a large family of stony S-type asteroids with nearly two thousand known members.[16]: 23  It was an outer Mars-crossing asteroid with perihelion less than 1.666 AU[1] 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.[17][needs update]

Brucia has a synodic rotation period of 9.463 hours (as of 1998).[4] 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.[8]
