HD 69830 c

It is the second-closest planet in its system and has a minimum mass 12 times that of Earth.

Based on theoretical modeling in the 2006 discovery paper, it is likely to be a rocky planet, not a gas giant.

[1] However, other work has found that if it had formed as a gas giant, it would have stayed that way,[3] and it is now understood that planets this massive are rarely rocky.
