Cómo se descubrió

Primer planeta descubierto en 2000, por velocidad radial (NASA Exoplanet Archive).

Sus planetas

HD 160691 b — about 1,400 times Earth's mass; its year lasts 650 days; about −11 °C, below freezing; found in 2000 by radial velocity.
HD 160691 d — 3.2 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 10 days; about 630 °C, hotter than boiling water; found in 2004 by radial velocity.
HD 160691 e — about 2,200 times Earth's mass; its year lasts 310 days; about 55 °C, between freezing and boiling; found in 2006 by radial velocity.
HD 160691 c — about 1,400 times Earth's mass; its year lasts about 11 Earth years; about −120 °C, below freezing; found in 2004 by radial velocity.

De dónde proceden estos datos

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.
