# The TOI-2458 system

TOI-2458 is an F9-F9.5 yellow-white star in Orion, 368.4 ly away, with 2 known planets. Their orbits run from 0.0482 to 0.129 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-2458-b) | 0.0482 | 3.737 d | 2.83 R⊕ | 13.3 M⊕ | 1509 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.
