HD 20782 b is a gas giant exoplanet that orbits a G-type star. HD 20782 b; HD 20782 b is an exoplanet orbiting the star HD 20782, located about 116.9 light-years (35.9 pc) away from Solar System. The Star HD 20782 's habitable zone is located at the following distance Inner Boundary (the orbital distance at Venus's Equivalent Radiation ) : 0.674 AU ( 100835889.2 km)
Its mass is 1.4878 Jupiters, it takes 1.6 years to complete one orbit of its star, and is 1.3649 AU from its star. Selection Functions in Doppler Planet Searches
HD 21693 c was added. HD 21693 b was added. These systems possess a giant planet that crosses into the stellar habitable zone, thus effectively thwarting the possibility of habitable terrestrial planets. Its mass is 1.4878 Jupiters, it takes 1.6 years to complete one orbit of its star, and is 1.3649 AU from its … Hien huet eng visuell Magnitude vu 7,4 mag. J; Astrobiol., 10, 1 paper. Its discovery was publicly announced on 2006. Exoplanet HD 20782 b has the most eccentric orbit astronomers have ever seen. HD 20782 b is an extrasolar planet located approximately 117 light-years away in the constellation of Fornax, orbiting the star HD 20782. Its orbit resembles more a comet than a planet.
Yeager, J. Eberle, M. Cuntz HD 20782 is a 7th magnitude G-type main sequence star 117.5 light-years away from Earth, in the constellation of Fornax.

Although it is found that Earth-mass planets are eventually ejected from the habitable zones of these systems, the "Hill Radius Criterion" is identified as invalid for the prediction of when the ejection is actually occurring. The host star HD 20782 has apparent magnitude of 7.4, with absolute magnitude of 4.6. Above this boundary, planets will have climates like that of HD 20782 b — one that gets thrown from the deep fryer to the freezer and back again. In the case of HD 188015, the orbit of the giant planet is essentially circular, whereas in the case of HD 20782, it is extremely elliptical. The following plot shows the approximate location of the planets in this system with respect to the habitable zone (green) and the size of the star (red). The planet has a minimum mass twice that of Jupiter and orbits a star known as HD 20782, which is part of a wide binary star system with HD 20781. HD 20782, located nearly 117 light-years from Earth, has an eccentricity of 0.96, meaning its orbit is a nearly flat ellipse. The Habitable Zone Gallery is now connected to the NASA Exoplanet Archive, ensuring that it will be constantly up-to-date with all the latest exoplanet discoveries.

On the ejection of Earth-mass planets from the habitable zones of the solar twins HD 20782 and HD 188015 - Volume 10 Issue 1 - K.E. HD 20782 is a part of a wide binary system in which the other star is designated HD 20781 , and both stars host planetary systems. Its orbit resembles more a comet than a planet. HD 20782 b spends a part of it’s orbit on the outer edge of the planets habitable zone where I would expect it temperature to drop. HD 31527 c was added. Pluto Mercury Mars Venus Earth Neptune Uranus Saturn Jupiter HD 20782 b HD 20781 b HD 20781 c Habitable zone. This is only an estimate, using the star's spectral type and mass.
