Kids may think that a planet would only have one moon, maybe two. But the larger outer planets, the gas giants, have many moons - Jupiter and Saturn leading the count with more than 60 moons each! What's more, the moons of Jupiter are not all just round, gray rocks - they are extremely varied, from volcanic Io, covered with volcanic activity; to Europa, with an icy surface covering an underground ocean; to Ganymede, a moon so large it's actually bigger than the planet Mercury!
- This is the first full episode to feature Face 9000's redesign.
- Mindy says that her parents are thinking about having a baby, but nothing else is revealed about it in any other episode.
- As of 2019, this episode is outdated, as Jupiter now has 79 confirmed satellites.
