Countless stars, eight recognized planets, and many other smaller planetary bodies, including comets, asteroids, and dwarf planets make up what we know to be our solar system.

There is so much to learn and explore!
To spark a love of astronomy and planetary science, we’ve collected resources that span the solar system and touch on a variety of topics. From the makeup of our eight planets to what lies at the far reaches of our solar system, the universe is just waiting to be uncovered by a new generation of young scientists.
