HAT-P-70 and Its Lone Known Planet
HAT-P-70 is a star 1080 light-years away. It is 0.6 billion years old, with a mass of 1.89 solar masses and a radius of 1.86 solar radii. Its temperature is 8450 K.
One planet orbits this star: HAT-P-70 b. Its radius of 21 Earth radii places it among the Jupiter-like planets, a class that exceeds 4 times Earth's radius. It was found by transit, the dimming of a star's light as a planet crosses in front of it. Its mass is 2150 Earth masses, roughly 6.78 times Jupiter's mass, and its mean density is 1.29 g/cm³. It completes an orbit every 2.74 days.
