Phocaea family
Encyclopedia
The Phocaea asteroids are a group of asteroids that orbit the Sun
between 2.25 and 2.5 AU
. Asteroids in this group have orbits with eccentricities
greater than 0.1 and inclination
s between 18 and 32. The group derives its name from its most massive member, 25 Phocaea

Orbital eccentricity
The orbital eccentricity of an astronomical body is the amount by which its orbit deviates from a perfect circle, where 0 is perfectly circular, and 1.0 is a parabola, and no longer a closed orbit...

Inclination
Inclination in general is the angle between a reference plane and another plane or axis of direction.-Orbits:The inclination is one of the six orbital parameters describing the shape and orientation of a celestial orbit...

25 Phocaea
25 Phocaea is a main-belt asteroid.It was discovered by J. Chacornac at Marseille, on April 6. 1853. It was his first asteroid discovery out of a total of six. It is named after Phocaea, the ancient Greek name for Foça in Turkey, from where came the founders of Marseille.-References:...
