StarStrider is a software planetarium that utilizes the latest in 3D-technology in order to show you not only the planets and satellites of our solar system, but also the more than 100,000 stars, all in real-time 3D.

You'll also find galaxies, nebulae, supernova remnants, and the band of the Milky Way. StarStrider combines photo realism and scientific accuracy with plain fun and beautiful vistas. Optional add-on with 2 million stars.

StarStrider is a software planetarium, a virtual space-ship, an advanced 3-dimensional star chart, a solar system simulator, and more... It is both fun and educative, it is pure beauty and it is scientifically accurate at the same time. It is our hope that it will not only give you a glimpse at the wonders of the universe but also that it will inspire you with some of the awe that we feel for the universe.
