Printable Solar System Word Search

A solar system word search is a quick way to review the planets and space vocabulary before a test. Seeing words like Jupiter, orbit, and eclipse a few times in a grid helps them stick better than a plain list.

The words cover the planets, the sun and moon, and the motions and objects around them, so it fits an astronomy or earth-science unit. Print it with the answer key, or open the list in the maker and narrow it to the exact topic — just the planets, say.
