Planets scaled to sit on your desk, hold in your hand or collect in jar, these micro-wonders let you collect constellations, moons, even entire solar systems.

Made by the Little Planet Factory in London, these 3D-printed models come with various degrees of detail, from real (raised ridges for Earthen land forms) to speculative (terraformed versions of Mars).

Collectors can choose entire sets and series that work in tandem, illustrating just how big Jupiter is and how small our own Terra can be, or pick individual bodies, like a larger-sized version of the moon.

Their creations get particularly inventive when they enter Russian doll territory, allowing you to select versions inside other versions, like Venus with and without its surrounding gas clouds (open the shell to get the latter).
