The purpose of this work is to follow the development of an application that allows realistic and precise visualization of astronomical catalogs in a virtual, navigable and interactable 3D environment.The software was built with the help of ALTEC SPA - an aerospace logistics company - and the game engine Unity3D that, despite its precision and performance limitations, offers greater simplicity, updatability and stability than a self-produced graphic engine.This application could be useful for astronomers to visualize data obtained by roaming satellites - like Hipparcos or Gaia - in order to infer new information and characteristics of celestial bodies, just by analyzing their position and parameters.
