You can download and print NASA’s “Solar System and Beyond” Poster Set for free. The posters are best printed on 11”x17” paper.
The space agency selected a collection of the most impressive photographs of Earth, solar system, and beyond.
The full set of “Solar System and Beyond” posters includes 21 deep space destinations and the planet Earth (with a variety of views and download options). You can see all the download options on solarsystem.nasa.gov.
On the backside of the images, you can find short explanations about the astronomical object(s). For example, the Solar System Version A poster comes with the description below:
“Our solar system is a planetary system composed of our star, the Sun, and all the objects that orbit around it – eight large planets, many smaller, planet-like worlds, dozens of moons, and millions of asteroids, comets, and meteoroids.”
“The planetary system we call home is located in an outer spiral arm of the vast Milky Way galaxy. Most stars have their own system of planets, meaning there are likely many billions of planetary systems in our galaxy alone (one of perhaps 100 billion galaxies). We’ve discovered thousands of these extrasolar planetary systems so far.”
Or there’s also an optional back with scale and orbit diagrams of the Solar System:
