About this world
HD 110113 c is a sub-Neptune orbiting HD 110113, a yellow, Sun-like star (type G) 347 light-years from Earth. It is about 2.1 times the size of Earth, with at least 11 Earth masses (a minimum, measured by radial velocity). It completes an orbit every 6.74 days at 0.068 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 990 K (717 °C): far too hot for liquid water on its surface. By the "cosmic shoreline", its star has probably stripped its atmosphere away, leaving bare rock.
It was discovered in 2021 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum. HD 110113 has 2 known planets; the others are HD 110113 b.
