HD 93963 A is 269 light-years from the Sun. The NASA Exoplanet Archive lists 2 planets around this G0 V star; the first was found in 2022 by transit (Transiting Exoplanet Survey Satellite (TESS)).
Fly there in 3DHD 93963 A b goes round its star every 24.9 hours, 85 times as often as Mercury goes round the Sun.
HD 93963 A is one of 2 stars in its system: the other is drawn where the Washington Double Star Catalog measures it on the sky.
| Spectral type | G0 V |
| Surface temperature | 5,908 K |
| Mass | 1.0844 solar masses |
| Radius | 1.0311 solar radii |
| Luminosity | 1.169 times the Sun |
| Apparent magnitude | 9.182 |
| Age | about 1.3 billion years |
| Distance from the Sun | 268.6 light-years (82.3 parsecs) |

HD 93963 B has no spectral type listed of magnitude 16.9, moving through space with it. In 2016 it was 5.9″ from HD 93963 A, at position angle 125° (Washington Double Star Catalog, 10511+2538 TOI1797): 486 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 |
|---|---|---|---|---|---|
| HD 93963 A b | 24.9 hours | 0.0206 AU | 1.4695 R⊕ | 2.8 M⊕ | Transit, 2022 |
| HD 93963 A c | 3.65 days | 0.0473 AU | 3.1198 R⊕ | 18.4 M⊕ | Transit, 2022 |
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 5,908 K, 1.2 times as bright as the Sun, the habitable zone, where starlight could keep water liquid on a rocky surface, runs from about 1.02 to 1.79 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.
