Scientists committed to naturalism continue to encounter dead ends in their search for habitable planets. A team of astronomers had claimed that an Earth-type planet capable of supporting life conceivably could exist in planetary systems like the one associated with the star 55 Cancri. The team found that a small planet could orbit 55 Cancri within the “habitable zone” where liquid water upon the planet’s surface would be possible if the planet had a rapid rotation rate and an atmosphere with the just-right greenhouse effect. However, for the planet to have a stable orbit with both a low eccentricity and inclination it would need to orbit 55 Cancri so closely that tidal locking would produce a rotation period for the planet far too long for life to survive. Earth and the solar system still appear unique in their capacity to support life.
