rocky planets
Solid surface spheres
Rocky planets are planets composed primarily of rock and metal, with solid surfaces—as opposed to gas giants like Jupiter and Saturn.
In our solar system, Earth, Mars, Venus, and Mercury are rocky planets.
The term is synonymous with terrestrial planets: The search for habitable rocky planets drives much of modern astronomy.
