What would a gas giant, such as Uranus, look like if it were orbiting a sun like star at an Earthlike orbit?
This is a hypothetical. If a gas giant with the approximate mass and density of Uranus existed within the goldilocks range to support life around a star, what would be the conditions on the service. ...
