Estrela com 2 planetas conhecidos

KOBE-1

KOBE-1, uma estrela K7 V, tem 2 planetas confirmados.

Medido

Sobre 78.2 anos-luz. Para atravessá-lo:

Voyager 1 à velocidade com que se afastou ao longo do ano até 2026-10-25 (JPL Horizons). Dirigindo: sem parar, sem nunca reabastecer.

Primeiro planeta descoberto em 2025 por velocidade radial (NASA Exoplanet Archive).

KOBE-1 c — 3.6 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 30 days; about 120 °C, hotter than boiling water; found in 2025 by radial velocity.
KOBE-1 b — 2.9 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 9 days; about 320 °C, hotter than boiling water; found in 2025 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.
