Detailed Description

Rectangular coordinates.

Rectangular Coordinates of a body. These coordinates can be either geocentric or heliocentric.

A heliocentric position is an objects position relative to the centre of the Sun. A geocentric position is an objects position relative to the centre of the Earth.

Position is in units of AU for planets and in units of km for the Moon.

Examples:

asteroid.c, comet.c, and lunar.c.
