Planets of the Solar System+50 
The planets of the Solar System are eight major celestial bodies that orbit the Sun, arranged by distance: Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, and Neptune. Each planet is unique in its size, composition, and atmosphere, ranging from rocky terrestrial planets to massive gas giants. Together, they form a dynamic system, accompanied by moons, asteroids, and other objects, all bound by the Sun’s gravitational pull.
