TOI-1201 is 124 light-years from the Sun. The NASA Exoplanet Archive lists 1 planet around this M2.0 V star; the first was found in 2021 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-1201 b goes round its star every 2.49 days, 35 times as often as Mercury goes round the Sun.
TOI-1201 is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.

TOI-1201 B has no spectral type listed of magnitude 13.46, moving through space with it. In 2019 it was 8.3″ from TOI-1201, at position angle 99° (Washington Double Star Catalog, 02490-1432 KPP2871): 314 AU on the sky at this distance. The true distance can only be larger. Its colour is estimated from its brightness.
| Planet | Year | Orbit | Radius | Mass | Found |
|---|---|---|---|---|---|
| TOI-1201 b | 2.49 days | 0.0287 AU | 2.415 R⊕ | 6.28 M⊕ | Transit, 2021 |
Values are the NASA Exoplanet Archive’s composite parameters. A radius marked estimated comes from a mass–radius relation; a mass marked minimum is M sin i. Planet sizes and colours in the 3D view are renderings: none of these worlds has been photographed as more than a point of light.
