Neptunian-sized planet orbiting HD 69830
HD 69830 c is an exoplanet orbiting HD 69830. 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. However, other work has found that if it had formed as a gas giant, it would have stayed that way, and it is now understood that planets this massive are rarely rocky.
