Stella con 3 pianeti noti

TOI-451

TOI-451, una stella G8 V, ha 3 pianeti confermati.

Misurato

Informazioni 404 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.

TOI-451 b — 1.8 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 45 hours; about 1,200 °C, hot enough to melt rock; found in 2020 by transit.
TOI-451 c — 2.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 9 days; about 590 °C, hotter than boiling water; found in 2020 by transit.
TOI-451 d — 3.9 times Earth's width, a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 16 days; about 440 °C, hotter than boiling water; found in 2020 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.
