Neptune - The Distant Blue Ice Giant of the Solar System #213521 (License: Personal Use)

This high-resolution image captures Neptune, the solar system’s fourth-largest planet by diameter and third-most-massive, distinguished by its rich azure appearance due to methane absorption. Faint cloud bands and subtle storms-including the Great Dark Spot observed by Voyager 2-are visible in detailed views. Its dynamic weather system features the strongest sustained winds in the solar system, exceeding 2,000 km/h.
