Phocaea group
Phocaea group A group of asteroids at a mean distance of about 2.36 AU from the Sun, with orbital inclinations of 23–25°. The group has been separated from the main asteroid belt by the gravitational effects of the major planets, notably Jupiter, and contains a broad selection of asteroid classes. The largest member of the group is the C-class (105) Artemis, diameter 126 km. Certain members, among them (323) Brucia, (852) Wladilena, (1568) Aisleen, and (1575) Winifred, may form a true family within the Phocaea group. The group is named after (25) Phocaea, an S-class asteroid, diameter 72 km, discovered in 1853 by the French astronomer Jean Chacornac (1823–73). Phocaea's orbit has a semimajor axis of 2.399 AU, period 3.72 years, perihelion 1.78 AU, aphelion 3.01 AU, and inclination 21°.6.
