Worlds Table Column Descriptions


Each line in the Worlds table represents a world, a small body, or a dynamical point.


The fields in the Worlds table are described below. The important fields are the name, mass, and radius. The orbital data given (columns from SemiMajorAxis through Epoch, and EphPeriod), as well as the RotPeriod, are sample values and it should be noted that the elements are functions of time - especially for moons. In practice, detailed ephemerides such as the JPL data are used to compute the locations of the worlds, and the values in this table are just to give the reader a general idea.
