Provided they host thick, hydrogen-dominated atmospheres, moons orbiting free-floating exoplanets could retain much of the heat generated deep within their interiors by tidal forces. Led by David ...

Free-floating planets could host moons with tidal heating and thick, hydrogen-rich atmospheres that may be able to create billions of years of potentially habitable surface conditions.
