CoRoT-8b is a transiting exoplanet orbiting the K-type main sequence star CoRoT-8 1,050 light years away in the equatorial constellation Aquila.

The planet was discovered in April 2010 by the CoRoT telescope.

The discovery paper's abstract states that CoRoT-8b is extremely dense compared to Saturn.

This classifies the planet as a hot Saturn.

Despite the bloated radius, the planet is extremely dense, with it being 1.1 times greater than water's; CoRoT-8b has a temperature of 870 K from its 6-day orbit.
