description HD 72659 b Overview
HD 72659 b is a gas-giant exoplanet orbiting the solar-type star HD 72659. It was detected through radial-velocity measurements and completes one orbit in roughly 3.6 years. The planet has a minimum mass several times that of Jupiter, so the term Jupiter analog refers mainly to its broad orbital scale and giant-planet nature rather than to an exact match with Jupiter. It is studied as an example of a long-period planet around a Sun-like star.
help HD 72659 b FAQ
How long is a year on HD 72659 b?
HD 72659 b completes one orbit in roughly 3.6 years. Its long period is one reason it is discussed as a Jupiter analog, although the comparison is limited.
Why is HD 72659 b called a Jupiter analog?
The term refers mainly to its wide, long-period orbit around a solar-type star. Its minimum mass is several times Jupiter's mass, so it is not a close mass match to Jupiter.
How was HD 72659 b detected?
It was detected through radial-velocity measurements of the star HD 72659. The planet's gravity causes a repeating motion in the star that can be measured spectroscopically.
What type of planet is HD 72659 b?
It is a gas giant orbiting the solar-type star HD 72659. Its minimum mass is several times Jupiter's, although radial-velocity data provide a minimum rather than always the exact mass.
