Eccentricity:

a parameter that specifies the shape of a conic section; one of the standard elements used to describe an elliptic orbit.

Perihelion::

the point at which a body in orbit around the Sun most closely approaches the Sun.

Period:

the interval of time required to complete one revolution in an orbit or one cycle of a periodic phenomenon, such as a cycle of phases.
