No one agrees what it means for a planet to be "habitable". Neel V. Patel, MIT Technology Review. 2 October 2019. Quote: surface conditions are dependent on a host of different individual properties of that planet, such as internal and geological processes, magnetic field evolution, climate, atmospheric escape, rotational effects, tidal forces, orbits, star formation and evolution, unusual conditions like binary star systems, and gravitational perturbations from passing bodies.
