Detailed Description

A subclass of TrailObject that provides additional information needed for most solar system objects.

This is a base class for KSSun, KSMoon, KSPlanet, KSAsteroid and KSComet. Those classes cover all solar system objects except planetary moons, which are derived directly from TrailObject

Provides necessary information about objects in the solar system.
