description HD 202206 c Overview
HD 202206 c is a massive outer planet in the HD 202206 system, detected from the radial motion of its host star. Its minimum mass is about 2.4 times that of Jupiter, and it follows a multi-year orbit outside the system’s much more massive inner companion, whose mass lies near the planet-brown-dwarf boundary. The arrangement is notable for its hierarchical architecture and for the dynamical interactions expected between the two companions.
help HD 202206 c FAQ
How massive is HD 202206 c?
Its minimum mass is about 2.4 times Jupiter's mass. The value is called a minimum because radial-velocity data do not always reveal the orbital inclination.
Where does HD 202206 c orbit?
It is the massive outer planet in the HD 202206 system. It orbits outside the system's much more massive inner companion, whose mass is near the brown-dwarf range.
How was HD 202206 c detected?
It was detected from the radial motion of its host star. The star's motion provided evidence for a large planet on a multi-year outer orbit.
Is HD 202206 c the most massive object in its system?
No. The inner companion is described as much more massive and near the brown-dwarf range. HD 202206 c is the outer planet with a minimum mass of about 2.4 Jupiters.
