Physicist proposes human-populated mega-satellite orbiting Ceres

Physicist Pekka Janhunen with the Finnish Meteorological Institute has developed a novel idea to colonize a place other than the Earth--and it is not the moon or Mars. Instead, Janhunen is suggesting in a paper posted on the arXiv preprint server that humans populate a giant satellite that orbits Ceres, a dwarf planet in the asteroid belt between Jupiter and Mars.
