About this world
HD 160691 e is a gas giant orbiting HD 160691, a yellow, Sun-like star (type G3IV-V) 50.9 light-years from Earth. It is about 1.1 times the size of Jupiter (its size estimated from its mass) and holds 7 Jupiter masses. It completes an orbit every 308 days at 0.96 AU from its star.
Its equilibrium temperature is about 328 K (55 °C): too cold for liquid water on its surface. At its size it almost certainly keeps a deep envelope of hydrogen and helium.
It was discovered in 2006 by radial velocity with La Silla Observatory. The star wobbles toward and away from us, Doppler-shifting its spectrum. HD 160691 has 4 known planets; the others are HD 160691 d, HD 160691 b and HD 160691 c.
