Come è stato scoperto

Primo pianeta scoperto nel 2017 con il transito (NASA Exoplanet Archive).

I suoi pianeti

K2-133 b — 1.3 times Earth's width, about Earth-sized — probably rocky; its year lasts 3 days; about 390 °C, hotter than boiling water; found in 2017 by transit.
K2-133 d — 2 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 11 days; about 460 °C, hotter than boiling water; found in 2017 by transit.
K2-133 c — 1.6 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 5 days; about 300 °C, hotter than boiling water; found in 2017 by transit.
K2-133 e — 1.7 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 27 days; about 23 °C, between freezing and boiling; found in 2019 by transit.

NASA Exoplanet Archive, Planetary Systems Composite Parameters (fetched 2026-11-02). Composite values: where a planet's size or mass was not measured, the archive estimates it from the other.
This research has made use of the NASA Exoplanet Archive, which is operated by the California Institute of Technology, under contract with NASA under the Exoplanet Exploration Program.
