How it was found
First planet found in 2003, by radial velocity (NASA Exoplanet Archive).
Its planets
HD 190360 b — 14 times Earth's width (estimated from its mass, not measured), a giant, Jupiter-sized or more; its year lasts about 8 Earth years; about −120 °C, below freezing; found in 2003 by radial velocity.
HD 190360 d — 3.5 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 89 days; about 190 °C, hotter than boiling water; found in 2026 by radial velocity.
HD 190360 c — 5.5 times Earth's width (estimated from its mass, not measured), Neptune-sized; its year lasts 17 days; about 520 °C, hotter than boiling water; found in 2005 by radial velocity.
