NASA and JPL have a very neat set of travels posters for Solar System and Interstellar vacation destinations at http://www.jpl.nasa.gov/visions-of-the-future/
You can download these as poster-quality PDFs!
If you download a poster, you’ll come to this screen that has more goodies.
I used Planet Quest by JPL often when researching for the first book in my Elise t’Hoot series; I wanted to get the latest facts on the exoplanets. FYI, exoplanets are the worlds that orbit suns not our own and it’s amazing how many they’re found. They have lots if the latest news on planets, asteroids, satellites, space, and have many helpful pictures to illustrate the concepts. Now they have lots of interactive stuff as part of the “Exoplanet Travel Bureau”.
All the pictures for this post are from the NASA JPL s1te, I hope you try it out and have fun!
