Mercury has the oldest and least changing surface among the Terrestrial Planets in our solar system. Its surface is heavily cratered and has remained relatively unchanged for billions of years due to its lack of atmosphere to weather or erode the surface features.
Earth is the most massive terrestrial planet, so it has the highest surface gravity.
Venus is considered a terrestrial planet because it has a solid surface, similar to Earth. It is often referred to as Earth's "sister planet" due to its similar size and composition.
Jupiter is a gaseous planet. It is composed mainly of hydrogen and helium and does not have a solid surface like terrestrial planets.
Mercury has the highest surface gravity of the terrestrial planets. Its gravity is about 0.38 times that of Earth's gravity.
