Semi-amplitude | 115 ± 12 |
Star | HD 20782 |
HD 20782 b is an extrasolar planet located approximately 117 light-years away in the constellation of Fornax, orbiting the star HD 20782.
This planet orbits in the most eccentric orbit known (as of November 2012), [1] with a semi-major axis of 1.36 AU, and eccentricity e=0.97+/-0.01. [2] As a result, it also has one of the most extreme temperature swings.
