Proxima b belongs an Unknown Planet Class and an Unknown Earth Similarity Class Percent.
More data is needed to determine its Planet Class and Earth Similarity Class.

Proxima b is a Cold Super Terran-sized planet with an unknown atmosphere. It has an unknown core and unknown crust with unknown gravity. It probably has a rocky surface. It is unknown if Proxima b has any life, however it believed the chances are small.

Proxima b orbits in the habitable zone of the Proxima Centauri Star. However, it is believed that Proxima b is tidally locked with the Proxima Centauri Star and is subjected to Extreme Flares from the Proxima Centauri Star. The habitable zone is defined as the zone where a planet has the opportunity to host liquid water on its surface given the planet has the appropriate atmosphere and temperature. Just because a planet is in this zone does not automatically make it habitable.
