The recent fly-by of Pluto by New Horizons got me to wondering: have any binary planets ever been discovered?

I know that Pluto and its moon Charon are quite close together and I wondered if anyone has ever measured to see if they’re orbiting each other in a binary system, rather than as a moon orbiting a planet. And whether or not it’s true of Pluto and Charon, is it possible for two planets to orbit each other?

Anyone?
