Publisher's blurb: Not all planets are the same, even those made of the same materials with the same atmosphere or those of the same size. Some have a purpose, whilst others have quirks about them that make them stand out. Presented here are 100 planetary aspects and quirks, to help give you an idea about the flavour or basic special details about the planet in question. This ranges from an orbit that goes “against the grain”, to a planet used a military testing grounds.
