Outer Planets and Their Characteristics

The video explores the outer planets of our solar system, known as Jovian planets or gas giants, which include Jupiter, Saturn, Uranus, and Neptune. These planets are characterized by their large size, gaseous composition, rings, and numerous moons. Jupiter is the largest, with a rapid rotation and a famous storm called the Great Red Spot. Saturn is renowned for its prominent ring system and is currently being studied by the Cassini spacecraft. Uranus, discovered by William Herschel, has a unique composition and rotation. Neptune, the most distant, was visited by NASA's Voyager 2 in 1989.
