Concentrations of radionuclides in rocky planet mantles may be critical for the habitability of Earth-like planets. Such planets with higher abundances likely lack

habitable. Several other planets, such as Gliese 180 b, also appear to be examples of planets once considered potentially habitable but later found to be

The theorized habitability of red dwarf systems is determined by a large number of factors. Modern evidence suggests that planets in red dwarf systems

hycean planets may exist even in the absence of stars, e.g. rogue planets. Although the presence of water may help them be habitable planets, their habitability

Natural satellites are expected to outnumber planets by a large margin and the study of their habitability is therefore important to astrobiology and the
