About these space puzzles
Space vocabulary has a built-in sense of scale: a moon crater, a planet, a galaxy, a light year. These lists move outward from what you can see on a clear night to the machines people have sent beyond it.
The Moon Watching list pairs well with a real evening outdoors — every word on it describes something you can see with your own eyes over the course of a month.
What makes each list different
- The Solar System — Planets and other bodies orbiting our Sun.
- Stars and Constellations — Named stars, constellations and stellar objects.
- Space Exploration — Spaceflight hardware, people and procedures.
- Moon Watching — Lunar phases and features visible with the naked eye.
Tips for space word searches
- Planet names share many letters (MARS, SATURN, URANUS). Look for the less common letters J, P and V first.
- Constellation names like CASSIOPEIA have doubled letters that stand out in a grid.
Every puzzle here can be played online, printed in standard or large print, or downloaded as a PDF with its answer key on US Letter or A4. To combine several into one PDF, use the printable pack builder.
