About this quiz

The set is the nineteen moons big enough to have pulled themselves round, plus Phobos and Deimos, plus Pluto's four small moons. Hundreds of smaller named moons exist and are deliberately left off.

Matching happens on every keystroke, so there is nothing to press. Each answer also takes its common alternates. Give up at any time and the ones you missed appear in outline. Your best score is kept in this browser only.

Nothing you type is sent anywhere. The only thing this page records is that the quiz finished, and the score.
