The term that describes a planet's ability to support life is "habitability." This concept considers various factors that allow for the existence of life, including the presence of liquid water, an atmosphere, suitable temperatures, and chemical nutrients. In astrobiology, researchers assess whether other celestial bodies, such as exoplanets or moons, have conditions that could potentially harbor life forms. Earth is the only known planet that meets all these conditions, but the search for habitable zones beyond our planet is a significant aspect of modern scientific exploration and offers insights into the possibility of extraterrestrial life.
