Phocaea family

The Phocaea family (/foʊˈsiːə/ foh-SEE-ə; adj. Phocaean; FIN: 701) is a collisional family of asteroids located between 2.25 and 2.5 AU in the inner region of the asteroid belt. Phocaea asteroids are of stony S-type composition and have orbits with eccentricities greater than 0.1 and inclinations between 18 and 32°.[1] The family has an estimated age of 2.2 billion years and derives its name from its most massive member, 25 Phocaea which is about 75 km in diameter. Several Phocaean asteroids are also Mars-crossers.[2][3]: 23
