The Kepler-529 system contains 3 exoplanets. It is located 2606.01 light years away from the solar system.
| Mass | 1.07 solar masses |
| Radius | 1.14 solar radiae |
| Temperature | 6087 kelvin |
| Stellar Metallicity | -0.1 decimal exponent |
| Age | 3.98 billion years |
At 4.134 Earth masses, Kepler-529 b 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.
