Earth-like planet
Potentially colonizable exoplanet
An Earth-like planet is a world with characteristics similar to Earth—rocky composition, moderate size, and conditions potentially suitable for liquid water.
The term appears frequently in discussions of exoplanets and the search for extraterrestrial life: Astronomers discovered an Earth-like planet in the habitable zone of a nearby star.
Also called an Earth analog or terrestrial planet, though terrestrial has a broader technical meaning in astronomy.
