Solar System - Terrestrial Planets [Earth, Mars] + Moon.

Terrestrial Planets (Brief Summary) Similar to Earth, close to the Sun, small in mass and volume, and high in density. Composed of solid elements, with few or no moons. Earth The third planet orbiting the Sun in our solar system. It is the largest rocky planet in our solar system. It is the only celestial body confirmed to harbor life, formed 4.6 billion years ago, and has a satellite, the Moon. Its main constituent elements are iron, oxygen, silicon, carbon, and magnesium. It has the highest density among all planets and dwarf planets. Moon Earth's only natural satellite and the closest satellite to the Sun. Eclipses, both solar and lunar, occur. A total solar eclipse happens because the Moon is about 400 times smaller than the Sun and about 400 times closer, allowing it to completely obscure the Sun. Also, because the Moon's rotation period and orbital period are the same, we can only see the near side of the Moon from Earth. Mars The fourth planet in the solar system, characterized by a desert landscape with a reddish hue due to iron oxide. It is called Mars for this reason. It appears brighter than Jupiter from Earth, ranking after the Sun, Moon, and Jupiter in brightness, and has a lower apparent magnitude than Jupiter.
