Everything you need to know about a Planet, Dwarf Planet or major moon presented on single datasheets for quick and easy reference. These are compiled into a PDF booklet which currently includes:

- Planets: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune
- Dwarf Planets: Ceres, Pluto, Eris, Makemake, Haumea
- Major Moons: The Moon, Europa, Io, Titan, Enceladus, Miranda, Triton

Each sheet features a table of numerical data showing a like-for-like comparison with Earth. This is shown alongside graphics for the orbit, atmospherical make-up and compositional layers. On the bottom half of the sheets is a list of bullet-point "headline" facts about each object, together with a list of space probes that have visited. Every sheet also has a photograph taken from the NASA Image & Video library, or a credited artist's impression for those more obscure bodies that have not been imaged or visited yet.
