Come è stato scoperto

Primo pianeta scoperto nel 2000 con la velocità radiale (NASA Exoplanet Archive).

I suoi pianeti

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.
