This image shows Neptune, the fourth-largest planet by diameter and the smallest by mass among the gas giants, with a vivid blue appearance due to methane absorption. Its dynamic atmosphere features the fastest winds in the Solar System-reaching over 2,000 km/h-and prominent storm systems like the Great Dark Spot. Neptune orbits the Sun every 165 Earth years and has 14 known moons, including Triton, which orbits retrograde.
