Stella con 3 pianeti noti

YZ Cet

YZ Cet, una stella M4.5 V, ha 3 pianeti confermati.

Misurato

Informazioni 12.1 anni luce. Per attraversarlo:

Voyager 1 alla velocità con cui si è allontanata nell'anno fino al 2026-10-25 (JPL Horizons). In auto: senza sosta, senza mai fare rifornimento.

Primo pianeta scoperto nel 2017 con la velocità radiale (NASA Exoplanet Archive).

YZ Cet d — 1 times Earth's width (estimated from its mass, not measured), about Earth-sized — probably rocky; its year lasts 5 days; about 84 °C, between freezing and boiling; found in 2017 by radial velocity.
YZ Cet b — 0.9 times Earth's width (estimated from its mass, not measured), about Earth-sized — probably rocky; its year lasts 2 days; about 200 °C, hotter than boiling water; found in 2017 by radial velocity.
YZ Cet c — 1.1 times Earth's width (estimated from its mass, not measured), about Earth-sized — probably rocky; its year lasts 3 days; about 140 °C, hotter than boiling water; found in 2017 by radial velocity.

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.
