This started out as an orbital mechanics simulator, built with simulation of spacecraft trajectories under the influence of gravity in mind. It got a star data loader grafted on, and will eventually be of use for generating 2D and 3D star maps. There's not much of a user interface at the moment, but hopefully I'll eventually have something releasable.
