... It is difficult to omit extrinsic characteristics. Modern cosmogony indicates that all planets are closely associated with stars. Planets are in orbit around stars and vice-versa. Also there are no known “orphan” planets wandering through the galactic disk. And the formation of stars by the condensa ...
