Which planet is famous for its "spot" known as the Great Dark Spot?

The correct answer is Neptune, which is renowned for the Great Dark Spot, a massive storm system resembling a hurricane that was first observed by the Voyager 2 spacecraft during its flyby in 1989. This similar feature showcases the dynamic and active atmosphere of Neptune, which is composed primarily of hydrogen, helium, and methane. The presence of methane gives the planet its characteristic blue color, and the Great Dark Spot itself is an indicator of the intense weather patterns and high-speed winds present in Neptune's atmosphere.

This dramatic storm can change in size and intensity over time, highlighting the planet's atmospheric dynamics. Unlike many of its neighbors, Neptune's Great Dark Spot provides a fascinating example of weather phenomena beyond Earth, making it a significant point of interest for astronomers and planetary scientists.
