I suoi pianeti

TOI-178 b — 1.2 times Earth's width, about Earth-sized — probably rocky; its year lasts 46 hours; about 770 °C, hotter than boiling water; found in 2021 by transit.
TOI-178 c — 1.8 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 3 days; about 600 °C, hotter than boiling water; found in 2021 by transit.
TOI-178 d — 2.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 7 days; about 420 °C, hotter than boiling water; found in 2021 by transit.
TOI-178 e — 2.3 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 10 days; about 330 °C, hotter than boiling water; found in 2021 by transit.
TOI-178 f — 2.4 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 15 days; about 250 °C, hotter than boiling water; found in 2021 by transit.
TOI-178 g — 2.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 21 days; about 200 °C, hotter than boiling water; found in 2021 by transit.
