Terrestrial planets, also known as rocky planets, are primarily composed of silicate rocks or metals and are characterized by their solid surfaces. These planets, including Earth, are located closer to the Sun within our solar system, distinguishing them from the gas giants and ice giants found in the outer regions.

Rocky planets

Silicate rocks are the most abundant rock type in the Earth's crust, primarily composed of silicate minerals that contain silicon and oxygen. These rocks form the foundation of the planet's lithosphere and play a crucial role in geological processes, including the rock cycle and the formation of various landforms.

Metals are elements characterized by their high electrical and thermal conductivity, malleability, ductility, and a lustrous appearance. They are typically solid at room temperature and are used extensively in construction, manufacturing, and technology due to their strength and versatility.

The solar system is a gravitationally bound system comprising the Sun and the objects that orbit it, including planets, moons, asteroids, comets, and meteoroids. It formed approximately 4.6 billion years ago from the gravitational collapse of a region within a large molecular cloud.
