Boiled down, a super Earth is an exoplanet that is between the Earth (and actually smaller than than Earth, I’m guessin’) but smaller than the Uranian-Neptunian “ice giants”. Oh, and it has to wear the cape.

Ah, I looked it up on Wikipedia, and, a bit to my surprise, the planet's makeup* has nothing to do with it: A superEarth is apparently defined by being "an extrasolar planet with a mass higher than Earth's, but substantially below those of the Solar System's ice giants, Uranus and Neptune, which are 14.5 and 17 times Earth's, respectively.

Even "substantially lower" (mass) is a bit of a loose constraint, I guess: 12.9x Earth vs. 14.5x does not seem a whole lot lower than Uranus, tho' we're getting there with Neptune (17x), I suppose. I propose 10x to 14x as "Super Duper Earths". Heheh. *Looking into this, I was reminded how cold Uranus atmosphere is, as low as -225 deg. C and 560 mph winds. Yikes!
