Triton
Neptune's largest moon that orbits the wrong way/Moons
Triton is the largest moon of Neptune and the only large moon in the solar system with a retrograde orbit, meaning it orbits backwards relative to its planet's rotation. This strongly suggests Neptune captured it from the Kuiper Belt, which is basically cosmic shoplifting. Its surface temperature of about 38 K makes it one of the coldest known objects in the solar system.
