# The HD 206893 system

HD 206893 is an F5V yellow-white main-sequence star in Capricornus, 125.1 ly away, with 2 known planets. Their orbits run from 3.74 to 11 AU. All of them were detected by imaging.

## The planets, innermost first

| Planet | Orbit (AU) | Period | Radius | Mass | Equilibrium T |
| --- | --- | --- | --- | --- | --- |
| [c](https://spacecatalog.org/object/hd-206893-c) | 3.74 | 6.27 yr | 16.37 R⊕ | 3530 M⊕ | 1182 K |

Every figure is the planet's composite parameter from the [NASA Exoplanet Archive (Planetary Systems Composite Parameters)](https://exoplanetarchive.ipac.caltech.edu/cgi-bin/TblView/nph-tblView?app=ExoTbls&config=PSCompPars), one consistent set per world. Semi-major axes are orbits about the star, not distances from Earth.
