Told in a soft, tender voice, "Jupiter" reads like a love poem addressed to someone who is afraid of the unknown. The speaker imagines that person as a space explorer who doesn't trust the stars, and offers to be a guide: "I've seen a few planets, I'll hold your hand." The stars are described with sweet, comforting flavors like honey, strawberry and cinnamon, as if the speaker wants to turn something frightening into something gentle.
The addressee has "Jupiter stuck in your eyes," which suggests the speaker finds something vast and beautiful in them. The final lines bring in Jupiter's moons. The speaker hopes to be Callisto, or would happily settle for Europa or Ganymede, which suggests a wish to stay close and orbit this person, even in a smaller role. The mood is warm, hopeful and a little shy, full of reassurance and quiet devotion.
