CoRoT-13 b: A Jupiter-Like Planet Orbiting a Sun-Like Star

CoRoT-13 is a G0 V star located 3750 light-years away, and it hosts one known planet. A G-type main-sequence dwarf of this kind is broadly Sun-like, and CoRoT-13's reported mass of 1.09 solar masses and temperature of 5950 K are both larger and hotter than the Sun's. The star is 1.01 solar radii across and 1.64 billion years old.

The one planet circling this star is CoRoT-13 b, a Jupiter-like world discovered by the transit method in 2010. A transit occurs when a planet crosses in front of its star as seen from Earth, dimming the star's light slightly and, when the dips repeat, revealing the planet's orbital period. CoRoT-13 b completes one orbit every 4.04 days. With a radius of 9.92 Earth radii, it is larger than Earth, and its mass of 416 Earth masses also exceeds Earth's - roughly 1.31 times Jupiter's mass. Its mean density is 2.35 g/cm³, 0.426 times Earth's.
