Exploring The Exoplanets [EP-2]
16 Cygni Bb or HD 186427 b is an extrasolar planet approximately 69 light-years away in the constellation of Cygnus.
The planet was discovered orbiting the Sun-like star 16 Cygni B, one of two solar-mass components of the triple star system 16 Cygni in 1996. It orbits its star once every 799 days and was the first eccentric Jupiter and planet in a double star system to be discovered. The planet is abundant in Lithium.

In October 1996 the discovery of a planetary-mass companion to the star 16 Cygni B was announced, with a mass at least 1.68 times that of Jupiter . At the time, it had the highest orbital eccentricity of any known planet. The discovery was made by measuring the star's radial velocity.
As the inclination of the orbit cannot be directly measured and as no dynamic model of the system was then published, only a lower limit on the mass could then be determined.
