Galaxiki is “a new kind of wiki based community portal that allows its members to edit stars, planets and moons in a virtual galaxy, creating an entire fictional world online.” The site uses primarily public domain NASA photography.

Millions of stars, planets, moons, pulsars and black holes can be explored using an intuitive 2D map. The site software manages most of the physical properties and behaviours of the solar systems, from orbits to the chemical composition of planetary atmospheres. Some planets offer conditions that may allow life – the idea behind Galaxiki is that community members can create fictional life forms and write about their histories on their planets….For only USD 12.- (or EUR 10.-) you can purchase your own solar system that only you can edit.
