Planetary engineering
open-in-new
<p>Planetary engineering is the development and application of technology for the purpose of influencing the environment of a <a href="/facts/Planet/rbPjE6Bx">planet</a>. Planetary engineering encompasses a variety of methods such as <a href="/facts/Terraforming/ny4dMbl1">terraforming</a>, seeding, and <a href="/facts/Geoengineering/yo7WTpGe">geoengineering</a>. </p><p>Widely discussed in the scientific community, terraforming refers to the alteration of other planets to create a habitable environment for terrestrial life. Seeding refers to the introduction of life from <a href="/facts/Earth/HLLmDfj0">Earth</a> to habitable planets. <a href="/facts/Climate_engineering/yo7WTpGe">Geoengineering</a> refers to the engineering of a planet's climate, and has already been applied on Earth. Each of these methods are composed of varying approaches and possess differing levels of feasibility and ethical concern. </p>
