A sub-Neptune exoplanet discovered in habitable zone of nearby star Gliese 555 (HN Lib)

Star system: Gliese 555 | Distance from the Sun: 20.4 light years

The planet Gliese 555 b could be rocky super-Earth and it could be habitable. Another candidate c was revealed by radial velocity data, if confirmed, it would most likely be an ice giant.
