How it was found
First planet found in 2017, by radial velocity (NASA Exoplanet Archive).
Its planets
HD 176986 d — 2.5 times Earth's width (estimated from its mass, not measured), a 'sub-Neptune' — bigger than Earth, smaller than Neptune; its year lasts 61 days; about 90 °C, between freezing and boiling; found in 2026 by radial velocity.
HD 176986 b — about 1,500 times Earth's mass; its year lasts 6 days; about 490 °C, hotter than boiling water; found in 2017 by radial velocity.
HD 176986 c — about 2,100 times Earth's mass; its year lasts 17 days; about 290 °C, hotter than boiling water; found in 2017 by radial velocity.
