Come è stato scoperto
Primo pianeta scoperto nel 2021 con il transito (NASA Exoplanet Archive).
I suoi pianeti
K2-352 d — 2.2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 15 days; about 450 °C, hotter than boiling water; found in 2021 by transit.
K2-352 c — 1.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 8 days; about 610 °C, hotter than boiling water; found in 2021 by transit.
K2-352 b — 1.4 times Earth's width, about Earth-sized — probably rocky; its year lasts 4 days; about 890 °C, hotter than boiling water; found in 2021 by transit.
