9 Space Jokes for Kids (Clean and Funny)
Clean space jokes for kids about planets, astronauts, rockets, and aliens - wordplay for the child who already has a favourite planet.
What makes these jokes work
Space jokes work especially well for children who have decided the universe is interesting. The subject comes pre-loaded: planets have memorable names, rockets are loud, and imaginary aliens make naturally silly characters.
Most of these punchlines are genuine wordplay rather than pure nonsense - "you planet" instead of "you planned it", a moon that is too full to eat dinner - so they suit the age when puns start landing hard, around seven and up.
Nothing here is frightening. No abductions, no explosions, no black holes swallowing anybody: the aliens in these jokes mostly want help with their gardens.
How to tell them
- "You planet" needs to be said quickly so listeners hear "planned it" first.
- Give each planet its own voice and one joke becomes a whole performance.
- These pair well with a space book or a trip to a planetarium gift shop.
- The alien jokes are the best entry point for younger children; the puns suit eights and up.

Around seven and up for the puns, since they turn on double meanings. Younger children still enjoy the silly pictures, especially anything involving an alien.
Do these space jokes teach science facts?
They use familiar space ideas such as planets, astronauts, and rockets, but the punchlines are playful wordplay rather than science lessons.
