The GJ 1061 system contains 3 exoplanets. It is located 11.98 light years away from the solar system.
| Mass | 0.12 solar masses |
| Radius | 0.16 solar radiae |
| Temperature | 2953 kelvin |
| Stellar Metallicity | -0.08 decimal exponent |
| Age | 7 billion years |
At less than 1.5 Earth masses, GJ 1061 b is a terrestrial planet, much like the terrestrial planets we find in our solar system, namely Mercury, Venus, Earth and Mars.

At 1.739 Earth masses, GJ 1061 c is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes.
| Mass | 1.740 Earth masses |
| Density | 5.820 grams per cubic centimeter |
| Radius | 1.180 Earth radiae |

At 1.641 Earth masses, GJ 1061 d is a so called Super Earth. Super Earths could be terrestrial worlds like Earth, but they could also be ocean worlds or terrestrial worlds wrapped in a substantial atmosphere, in which case some refer to them as Mini Neptunes. GJ 1061 d 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.
