Come è stato scoperto

Primo pianeta scoperto nel 2006 con la velocità radiale (NASA Exoplanet Archive).

I suoi pianeti

HD 69830 b — 3.2 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 600 °C, hotter than boiling water; found in 2006 by radial velocity.
HD 69830 d — 4.5 times Earth's width (estimated from its mass, not measured), Neptune-sized; its year lasts 200 days; about 35 °C, between freezing and boiling; found in 2006 by radial velocity.
HD 69830 c — 3.5 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 32 days; about 290 °C, hotter than boiling water; found in 2006 by radial velocity.
