Cómo se descubrió

Primer planeta descubierto en 2001, por velocidad radial (NASA Exoplanet Archive).

Sus planetas

HD 142 A d — 11 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 110 days; about 260 °C, hotter than boiling water; found in 2022 by radial velocity.
HD 142 b — 13 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts 350 days; about 85 °C, between freezing and boiling; found in 2001 by radial velocity.
HD 142 c — 12 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 28 Earth years; about −160 °C, below freezing; found in 2012 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.
