What is the central body of the Solar System?

The Sun is the central body of the Solar System due to its massive size and gravitational influence. It contains about 99.86% of the Solar System's total mass, making it the most significant celestial body. The Sun's gravitational pull is what keeps the planets, including Earth and Mars, in orbit around it.

In contrast, Earth, Mars, and the Moon do not have the same gravitational dominance; they are all bodies that orbit the Sun. Earth and Mars are planets, while the Moon is a natural satellite of Earth. The existence of the Sun at the center facilitates the structure and dynamics of the entire Solar System, including the orbits of the planets, moons, asteroids, and comets. Its energy is essential for life on Earth and influences the climate and atmospheres of other planets as well.
