A new website launched by the Jet Propulsion Laboratory and NASA allows users to fly through space and see how other discovered planets look. Users can also look at the sky from any place on the earth and see exactly where other stars and solar systems line up. You can also see the habitable zone produced by stars other than the sun and see exoplanet's orbits.
You can also look at how the other solar systems compare with the Earth's system.
This site kept me entertained for hours and only takes a simple download. Follow this link to the JPL website to get started!
