I suoi pianeti

HIP 41378 b — 2.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 16 days; about 690 °C, hotter than boiling water; found in 2016 by transit.
HIP 41378 c — 2.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 32 days; about 480 °C, hotter than boiling water; found in 2016 by transit.
HIP 41378 d — 3.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 280 days; about 94 °C, between freezing and boiling; found in 2016 by transit.
HIP 41378 e — 5.2 times Earth's width, Neptune-sized; its year lasts 390 days; about 62 °C, between freezing and boiling; found in 2016 by transit.
HIP 41378 f — 9.5 times Earth's width, Neptune-sized; its year lasts 540 days; about 21 °C, between freezing and boiling; found in 2016 by transit.
HIP 41378 g — 2.5 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 63 days; about 330 °C, hotter than boiling water; found in 2025 by radial velocity.
