Terraforming

Terraforming (literally, “Earth-shaping”) of a planet, moon, or other body is the process of deliberately modifying its atmosphere, temperature, surface topography or ecology to be similar to the biosphere of Earth, in order to make it habitable by humans.

The term is sometimes used more generally as a synonym for planetary engineering, although some consider this more general usage an error. The concept of terraforming developed from both science fiction and actual science. The term was coined by Jack Williamson in a science-fiction story (“Collision Orbit”) published during OE1942 in Astounding Science Fiction, but the concept may pre-date this work.
