HD 69830 b

HD 69830 b is a Neptune-mass or super-Earth-mass exoplanet orbiting the star HD 69830. It is 10 times more massive than Earth, making it the least massive known exoplanet in the system. It also orbits very close to its parent star and takes 82/3 days to complete an orbit.
This is likely to be a rocky planet, not a gas giant. If it had formed as a gas giant, it would have stayed that way.
If HD 69830 b is a terrestrial planet, models predict that tidal heating would produce a heat flux at the surface of about 55 W/m2. This is 20 times that of Io.
