# The TOI-1294 system

TOI-1294 is a star in Ursa Minor, 1085 ly away, with 2 known planets. Their orbits run from 0.0510 to 0.610 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-1294-b) | 0.0510 | 3.915 d | 10.12 R⊕ | 63.9 M⊕ | 1393 K |
| [c](https://spacecatalog.org/object/toi-1294-c) | 0.610 | 159.9 d | 14.30 R⊕ | 147 M⊕ | 440 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.
