Calvin the Astronaut
Calvin In Astronaut Form is a minor alter ego of Calvin's. He appeared in a single Sunday strip. In it, Calvin imagined himself as an Apollo Program astronaut writing "Calvin is great" on the moon, in lunar buggy tread tracks.

Calvin perceived the moon as being much smaller than it actually is, indicating a scientific ignorancee at odds with Calvin's apparent interest in the universe.
