Seus planetas

HD 3167 b — 1.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 23 hours; about 1,500 °C, hot enough to melt rock; found in 2016 by transit.
HD 3167 c — 3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 30 days; about 290 °C, hotter than boiling water; found in 2016 by transit.
HD 3167 d — 2.6 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 8 days; about 590 °C, hotter than boiling water; found in 2017 by radial velocity.
HD 3167 e — 4 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 92 days; about 120 °C, hotter than boiling water; found in 2022 by radial velocity.
