Input: Question: Which planet that Kepler is compared to has a larger mass? Passage 1:Kepler-8b has a mass of .603 M, but a radius of 1.419 R. This means that although Kepler is approximately 60% the mass of planet Jupiter, it is more diffuse, as it is 41.9% wider. Based on its size and the distance from its star, Kepler-8b is a Hot Jupiter planet, orbiting Kepler-8 from a distance of .0483 AU every 3.52254 days. To compare, planet Mercury orbits the Sun at an average distance of .3871 AU every 87.97 days. With an equilibrium temperature of 1764 K, Kepler-8b was the hottest of the five planets announced during the conference stating its discovery. Kepler-8b has an eccentricity of 0, which means that its orbit is very circular. The planet also has a density of .261 grams/cc, approximately 74% less dense than purified water at 4 °C.
