Oh please. Could do this since elementary school.
Mercury
Venus
Earth
Mars
Jupiter
Saturn
Uranus
Neptune
Pluto
From 1979 to 1999, Pluto was closer than Neptune.
Pluto is also in a 3:2 resonance orbit with Neptune, something which a number of small icy objects out that way share. (Ooh, aah, bonus points.)
And Pluto's orbital period is 247.7 years.

OK, my turn: without looking name the moons of jupiter.
Aren't there like, 250 billion moons around Jupiter or something? It's got loads of them.
4 Galilean Moons though:
Io
Europa
Callisto
Ganymede (which is larger than Mercury)
I think it's got more than 50 known moons though.
Saturn's largest, Titan, with an atmosphere denser than Earth's.
Uranus has got a funky moon, Miranda. And another moon: Umbriel. And a number of other ones.
Neptune: Triton and Nereid, plus a bunch more discovered by Voyager 2
Pluto: Charon, plus two other wee little ones discovered in the past few years.
