Right now the goal of SpaceX is to colonise Mars. This is the nearest planet that we could feasibly travel to and inhabit. Soon our technological capabilities will allow us to travel to, and live on, the red planet in a cost-efficient and sustainable way. Science fiction will become reality. But there is no reason that our thirst for space exploration and colonisation would end on the Red Planet. Many sci-fi books deal with the topic of space colonisation. Colonising planets other than Mars could become a reality in the future. But which ones planets are good candidates?
