Terraforming or terraformation ("Earth-shaping") is the hypothetical process of deliberately modifying the atmosphere, ... Mercury would be difficult to terraform.
Mercury is rich of metals and volatiles, as well as solar energy. However, Mercury is the most energy-consuming body on the Solar System to land for spacecraft launching from Earth, and astronauts there must contend with the extreme temperature differential and radiation.

It then passed close to Mercury on March 29, 1974, as it flew towards the Sun. This was the first observation made of Mercury at close range. After the encounter Mariner 10 was in an orbit around the Sun such that for every one of its orbits Mercury made two, and the spacecraft and the planet would be able to meet again. This allowed the probe ...
"Terraforming refers to modifying a planet's environment to make it more Earth-like. For Mars, warming the planet is a necessary, but insufficient, first step. Previous concepts have focused on ...
A common object of discussion on potential terraforming is the planet Mars. To terraform Mars, humans would need to create a new atmosphere, due to the planet's high carbon dioxide concentration and low atmospheric pressure. This would be possible by introducing more greenhouse gases to below "freezing point from indigenous materials". [2]
There is a roughly one percent chance that Jupiter's gravity may make Mercury's orbit so eccentric as to cross Venus's orbit by this time, sending the inner Solar System into chaos. Other possible scenarios include Mercury colliding with the Sun, being ejected from the Solar System, or colliding with Venus or Earth. [105] [106] 3.5–4.5 billion
This is a WikiProject meant to organize and coordinate development of Wikipedia entries on aspects of space colonization, terraforming, planetary engineering, and other subjects related to the medium and long term future of humans in space.
In the far future, humans might artificially produce an Earth analog by terraforming. Before the scientific search for and study of extrasolar planets, the possibility was argued through philosophy and science fiction. Philosophers have suggested that the size of the universe is such that a near-identical planet must exist somewhere.
