HD 5278 and Its Two Known Planets
HD 5278 is a single star of spectral type F V, an F-type main-sequence dwarf, located 188 light-years away. Its age is 3 billion years, with a mass of 1.13 solar masses and a radius of 1.19 solar radii, while its temperature is 6200 K. Two planets have been reported to orbit this host.
HD 5278 b is a Super-Earth discovered by the transit method in 2021. It has a reported mass of 7.8 Earth masses, a radius of 2.45 Earth radii, and an orbital period of 14.3 days. HD 5278 c was discovered by radial velocity in 2021 and has a minimum mass of 18.4 Earth masses, with an orbital period of 40.9 days. The star's reported mass is larger than the Sun's, its reported radius is larger than the Sun's, and its reported temperature is hotter than the Sun's. HD 5278 b's mean density is 2.92 g/cm³, 0.53 times Earth's.
