Learn about the 8 planets that make up our solar system with this convenient printable solar system diagram for kids. (If you thought there were 9, remember, Pluto has been demoted to a dwarf planet.) Starting with the planet closest to the sun, there’s Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and finally Neptune.
The solar system diagram is available in both color and black and white. It was created for classroom and educational use for students, parents and teachers. You may print it for any personal and educational project. The planets are roughly to scale relative to one another. You may not post this content on your own website.
I’ve also included a printable collection of the planets and the sun, wherein each planet is the same size. This may be useful for decorating posters and projects.
