Composition of Terrestrial Planets

• Primarily composed of rock and metal, providing a solid and dense structure.
• Surface comprised of minerals, with significant geological activity influencing their formation and evolution.

IAU Classification of Terrestrial Planets

Etymology of 'Terrestrial' and 'Telluric'

• 'Terrestrial' comes from the Latin word 'terra', meaning Earth.
• 'Telluric' also has roots in 'terra' and refers to Earth-like qualities in composition and structure.

Study of Terrestrial Planets

• Generally studied by planetary scientists and astronomers who focus on geology, atmospheric conditions, and potential for life.
• Involves interdisciplinary approaches, integrating knowledge from geology, chemistry, and biology.

Distinction from Gaseous Planets

• Terrestrial planets possess solid surfaces whereas gas giants are primarily composed of hydrogen and helium.
• Terrestrial planets are smaller in size and mass compared to the large gaseous giants like Jupiter and Saturn.
• Lack deep atmospheres and have relatively higher densities, facilitating a distinct planetary structure and surface features.
