Humans could move to this floating asteroid belt colony in the next 15 years, astrophysicist says

Now more than ever, space agencies and starry-eyed billionaires have their minds fixed on finding a new home for humanity beyond Earth’s orbit. Mars is an obvious candidate, given its relatively close proximity, 24-hour day/night cycle and CO2-rich atmosphere. However, there’s a school of spacefaring thought that suggests colonizing the surface of another planet — any planet — is more trouble than it’s worth.

Now, a new paper published Jan. 6 date to the preprint database arXiv offers a creative counter-proposal: Ditch the Red Planet, and build a gargantuan floating habitat around the dwarf planet Ceres, instead.
