In Recent Science protests around the USA, people protested varying issues related to science. But one claim stuck out, protesters claimed there is no planet b? It turns out rather recently scientists have in fact found 6 possible b habitable exoplanets within a conservative habitable zone and additional 14 b habitable exoplanets within an optimistic habitable zone. Of the 6 b habitable planets within a conservative habitable zone, 3 are found within 14 light years from earth. Even more, Proxima Centauri b is only 4.22 light years from earth.
Below is a list of b planets in the conservative habitable zone
This is a list of the exoplanets that are more likely to have a rocky composition (which according to current research requires a radius of less than 1.6 R⊕ and a mass less than 6 M⊕) and maintain surface liquid water (i.e. between 0.5 and 1.5 R⊕ and between 0.1 and 5 M⊕, and orbiting within the conservative habitable zone). Note that this does not ensure habitability, and that * represents an unconfirmed planet or planet candidate. Earth is included for comparison.

This is a list of the exoplanets that are less likely to have a rocky composition or maintain surface liquid water (i.e. 0.5 < planet's radius ≤ 1.5 Earth radii or 0.1 < planet's minimum mass ≤ 10 Earth masses, or the planet is orbiting within the optimistic habitable zone). Note that this does not ensure habitability, and that * represents an unconfirmed planet or planet candidate.
