Astronomers have discovered a new ocean world outside the solar system that orbits extremely close to its parent star. This means that the extrasolar planet, or "exoplanet," is in hot water, both literally and figuratively.
The exoplanet orbits the star HD 176071 located around 335 light-years away, and is about two and a half times the size of Earth, but has about eight and a half times the mass of our planet. That indicates to scientists that this planet is about 50% water. At a distance from its star of just under 1.5 million miles (about 1.6% of the distance between the Earth and the sun) and with a year lasting just 14 hours, HD 176071 b is a rare example of a "hot water world."
