Submission + - The Densest Planet In The Universe (So Far) (

RedEaredSlider writes: Astronomers have found what may be the biggest rocky planet in the neighborhood.

The planet is called 55 Cancri e. It is 60 percent larger than the Earth, eight times as massive and orbits its star so fast that an entire year passes in less than a day.

It is about 8.57 times the mass of Earth, plus or minus about 0.64 Earth masses. That gives a density of about 10.9 grams per cubic centimeter, twice that of Earth, which averages about 5.5 grams. The surface gravity would be about 2.7 times that of Earth, comparable to what one would feel at the cloud tops of Jupiter.
