About this world
HD 110067 e is a super-Earth orbiting HD 110067, an orange dwarf (type K0.0V) 105 light-years from Earth. It is about 1.9 times the size of Earth and holds 3.9 Earth masses. It completes an orbit every 30.8 days at 0.18 AU from its star, closer than Mercury is to the Sun.
Its equilibrium temperature is about 533 K (260 °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 2023 by transit with Multiple Observatories. A planet crosses its star and dims it by a tiny, periodic fraction. HD 110067 has 6 known planets; the others are HD 110067 b, HD 110067 c, HD 110067 d, HD 110067 f and HD 110067 g.
