TOI-1450 A is 73.2 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this M3.0 V star; the first was found in 2024 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DTOI-1450 A b goes round its star every 2.04 days, 43 times as often as Mercury goes round the Sun.
TOI-1450 A is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.
Where the archive gives only a period or only an orbit size, the other is worked out from Kepler’s third law with the star’s mass.
| Spectral type | M3.0 V |
| Surface temperature | 3,437 K |
| Mass | 0.48 solar masses |
| Radius | 0.483 solar radii |
| Luminosity | 0.02723 times the Sun |
| Apparent magnitude | 12.28 |
| Distance from the Sun | 73.2 light-years (22.4 parsecs) |
| Position (J2000) | RA 286.8541°, Dec 59.0866° |
| Constellation | Draco |
TOI-1450 B has no spectral type listed of magnitude 16.53, moving through space with it. In 2021 it was 3.2″ from TOI-1450 A, at position angle 325° (Washington Double Star Catalog, 19074+5905 KPP3335 AB): 71.8 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-1450 A b | 2.04 days | 0.0247 AU from Kepler’s law | 1.13 R⊕ | 1.258 M⊕ | Transit, 2024 |
| TOI-1450 A c | 5.07 days | 0.0452 AU from Kepler’s law | 1.13 R⊕ estimated | 1.527 M⊕ minimum | Transit, 2024 |
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.
For a star of 3,437 K, 0.027 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 0.17 to 0.33 AU. None of its known planets orbits inside it. The zone says how much starlight arrives, not whether a planet has water or air. The edges follow Kopparapu et al. (2014), as the 3D view draws them.
