# The TOI-1386 system

TOI-1386 is a G5V yellow main-sequence star in Lacerta, 479.0 ly away, with 2 known planets. Their orbits run from 0.173 to 0.750 AU. All but one were detected by transit.

## The planets, innermost first

| Planet | Orbit (AU) | Period | Radius | Mass | Equilibrium T |
| --- | --- | --- | --- | --- | --- |
| [b](https://spacecatalog.org/object/toi-1386-b) | 0.173 | 25.84 d | 6.22 R⊕ | 45.8 M⊕ | 615 K |
| [c](https://spacecatalog.org/object/toi-1386-c) | 0.750 | 232 d | 10.30 R⊕ | 75.2 M⊕ | 327 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.
