A couple more questions. Would the presence of a magnetic field affect habitability? If so how? How likely is a planet this size to have a magnetic field like Earth's? Say we did colonize this planet, would be be able to launch crafts into orbit from the surface? It seems like our rockets can barely escape Earth's gravity?
