HD 207496 and Its Super-Earth
HD 207496 is a K2.5 V star located 77 light-years away. Its reported mass, 0.8 solar masses, is smaller than the Sun's; its radius, 0.769 solar radii, is also smaller; and its temperature, 4820 K, is cooler. It is 0.52 billion years old. One planet orbits this host.
That planet is HD 207496 b, a Super-Earth discovered in 2023 by the transit method. It has a mass of 6.1 Earth masses and a radius of 2.25 Earth radii. Both values exceed Earth's corresponding measurements. Its mean density is 2.95 g/cm³, 0.536 times Earth's. The planet completes one orbit every 6.44 days.
