PLANETS
1. Jupiter
Jupiter is the largest planet in the Solar System, with a diameter about 11.2 times that of Earth. It is a gas giant composed mainly of hydrogen and helium and has no solid surface like Earth. Jupiter's strong gravity influences many objects in the Solar System and helps protect inner planets by attracting asteroids and comets. It is famous for the Great Red Spot, a giant storm larger than Earth that has existed for centuries. Jupiter has dozens of moons, including Ganymede, the largest moon in the Solar System. Its immense size makes it a dominant planetary body.
2. Saturn
Saturn is the second-largest planet in the Solar System, with a diameter approximately 9.5 times larger than Earth. It is a gas giant composed primarily of hydrogen and helium. Saturn is best known for its spectacular ring system, made of billions of ice and rock particles orbiting the planet. Despite its enormous size, Saturn has a very low density and could theoretically float in water if a large enough ocean existed. It has more than a hundred known moons, including Titan, which possesses a dense atmosphere. Saturn's unique rings make it one of the most beautiful planets.
3. Uranus
Uranus is the seventh planet from the Sun and has a diameter about four times that of Earth. It is classified as an ice giant because it contains large amounts of water, ammonia, and methane ices. Methane in its atmosphere gives Uranus its distinctive blue-green color. Unlike most planets, Uranus rotates on its side, likely due to a massive collision in the distant past. This unusual tilt causes extreme seasonal variations. Uranus has a faint ring system and numerous moons. Scientists study Uranus to better understand the formation and evolution of planetary systems.
4. Neptune
