description HD 10180 h Overview
HD 10180 h is a Neptune-class exoplanet detected through the radial-velocity motion of the Sun-like star HD 10180, about 127 light-years from Earth. It has a minimum mass of roughly 65 Earth masses and takes about six years to complete an orbit, placing it in the outer region of this multi-planet system. Because the radial-velocity method measures a minimum mass rather than a direct bulk mass, the planet’s true mass depends on the system’s orbital inclination.
help HD 10180 h FAQ
What kind of planet is HD 10180 h?
HD 10180 h is a Neptune-class planet detected from the radial-velocity motion of the Sun-like star HD 10180. Its minimum mass is roughly 65 Earth masses, making it one of the system's outer giant planets.
How long is a year on HD 10180 h?
HD 10180 h takes about six years to complete an orbit. Its long period places it in the outer region of the known HD 10180 system.
How far away is the HD 10180 system?
The system is about 127 light-years from Earth. Its host is a Sun-like star in the southern constellation Hydrus.
Was HD 10180 h found by observing a transit?
No, it was detected through radial-velocity observations of the star's movement. This technique is useful for finding massive outer planets but normally gives a minimum mass.
