Neptune - The Distant Blue Ice Giant of Our Solar System #3483665 (License: Personal Use)

This image depicts Neptune, the fourth-largest planet by diameter and third-most-massive in the Solar System. Its vivid blue coloration stems from methane gas absorbing red wavelengths, while high-altitude clouds of methane ice create delicate, swirling white streaks. The planet exhibits extreme weather, including the fastest sustained winds in the Solar System-reaching over 2,000 km/h.

Used on astronomy, space education, or planetary science web pages to illustrate Neptune’s visual characteristics; matches user intent for learning about outer planets, NASA missions (e.g., Voyager 2), or comparative planetology.
