Earth

A Terrestrial Planet (aka Earth-like world) is any silicate (rocky) planet orbiting a star. They all have a central metallic core, silicate mantel around that and a thin crust is a planet's surface. These planets are usually smaller than a gas giant. A planet with volcanic activity has liquid magma underneath the crust.[1]

Examples of terrestrial planets are Earth, Mercury, Mars and Venus are terrestrial planets with a similar composition, but a different surface and atmosphere.

An Earth-like world is a terrestrial planet with similar characteristics as Earth. There's a high probability that indigenous life evolved there compared to other planet types.
