HD 110067 is a star with six known sub-Neptune exoplanets (b, c, d, e, f, g) with radii ranging from 1.94 R⊕ to 2.85 R⊕. The planets orbit the host star in a rhythmic orbital resonance. The star, and related planetary system, is located 105 light-years away in the constellation Coma Berenices.[3][4][5][6][7][8][9][10]

HD 110067 is part of a wide triple star system, along with the spectroscopic binary system HD 110106.[11]
