# The HD 214573 system

HD 214573 is a K1III orange giant in Grus, 267.8 ly away, with 2 known planets. Their orbits run from 1.32 to 1.97 AU. All of them were detected by radial velocity.

## The planets, innermost first

| Planet | Orbit (AU) | Period | Radius | Mass | Equilibrium T |
| --- | --- | --- | --- | --- | --- |
| [HIP 111909 b](https://spacecatalog.org/object/hip-111909-b) | 1.32 | 487.1 d | 13.70 R⊕ | 385 M⊕ | 437 K |
| [HIP 111909 c](https://spacecatalog.org/object/hip-111909-c) | 1.97 | 893.6 d | 13.90 R⊕ | 257 M⊕ | 358 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.
