# The Kepler-1165 system

Kepler-1165 is a star in Lyra, 5138 ly away, with 2 known planets. Their orbits run from 0.0914 to 0.197 AU. All of them were detected by transit.

## The planets, innermost first

| Planet | Orbit (AU) | Period | Radius | Mass | Equilibrium T |
| --- | --- | --- | --- | --- | --- |
| [b](https://spacecatalog.org/object/kepler-1165-b) | 0.0914 | 9.479 d | 1.55 R⊕ | 3.02 M⊕ | 946 K |
| [c](https://spacecatalog.org/object/kepler-1165-c) | 0.197 | 29.97 d | 3.36 R⊕ | 11.2 M⊕ | 644 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.
