[[Freeman Dyson]] proposed that [[trans-Neptunian object]]s, rather than [[planet]]s, are the major potential habitat of life in space.<ref>{{Citationcite web|title=Let's look for life in the outer solar system |first=Freeman|last=Dyson |website=ted2003 needed|date=JanuaryFebruary 2003 |url=https://www.ted.com/talks/freeman_dyson_let_s_look_for_life_in_the_outer_solar_system?language=en |access-date=18 April 20162025}}</ref> Several hundred billion to trillion [[comet]]-like ice-rich bodies exist outside the orbit of [[Neptune]], in the [[Kuiper belt]] and Inner and Outer [[Oort cloud]]. These may contain all the ingredients for life (water ice, ammonia, and carbon-rich compounds), including significant amounts of [[deuterium]] and [[helium-3]]. Since Dyson's proposal, the number of trans-Neptunian objects known has increased greatly.

Colonists could live in the [[dwarf planet]]'s icy [[Crust (geology)|crust]] or [[mantle (geology)|mantle]], using [[fusion power|fusion]] or [[Geothermal power|geothermal]] heat{{Citation needed|date=January 2016}} and mining the soft-ice or liquid inner [[ocean]] for [[Volatile (astrogeology)|volatiles]] and [[mineral]]s. Given the light gravity and resulting lower pressure in the ice [[mantle (geology)|mantle]] or inner ocean, colonizing the rocky [[Planetary core|core]]'s outer surface might give [[colonists]] the largest number of [[mineral]] and [[volatility (chemistry)|volatile]] resources as well as insulating them from cold.{{Citation needed|date=January 2016}} Surface habitats or [[domes]] are another possibility, as [[background radiation]] levels are likely to be low.{{Citation needed|date=January 2016}}
