The Proxima Cen system contains 1 exoplanet. It is located 4.24 light years away from the solar system.
| Mass | 0.12 solar masses |
| Radius | 0.14 solar radiae |
| Temperature | 3050 kelvin |
| Stellar Metallicity | - decimal exponent |
| Age | - billion years |
At less than 1.5 Earth masses, Proxima Cen b is a terrestrial planet, much like the terrestrial planets we find in our solar system, namely Mercury, Venus, Earth and Mars. Proxima Cen b orbits within the habitable zone of its parent star and could, potentially, be a habitable planet with stable bodies of liquid water on its surface, like Earth.
