Neptune: The Distant Ice Giant

The video provides an overview of Neptune, the eighth planet from the Sun, highlighting its characteristics as a gas giant with a dense atmosphere composed mainly of hydrogen, helium, and methane. It discusses Neptune's active weather patterns, including the Great Dark Spot, and its strong winds. The discovery of Neptune through mathematical predictions is explained, along with its orbit and interaction with Pluto. The video also covers Neptune's rings and moons, particularly Triton, and concludes with Voyager 2's exploration and the potential for future discoveries.
