Planetary system dynamics

A planetesimal is a solid body in a young or evolved planetary system whose collisions and gravitational interactions help build or erode larger bodies.

Tisserand parameter ( $T_{p}$ )

For a small body with orbital elements

a, e, I

relative to a planet on a circular orbit of semi-major axis

a_{p}

, the Tisserand parameter is approximately

T_{p} = \frac{a _{p}}{a} + 2 \frac{a}{a _{p}} (1 - e^{2}) cos I .

It is derived from the Jacobi constant and is approximately conserved across separated weak encounters in the circular restricted three-body problem.
