The planet known for its storms and blue color is Neptune. Neptune is a deep blue planet due to the presence of methane gas in its atmosphere, which absorbs red light and reflects blue light. It is named after the Roman god of the sea, fitting its vivid blue appearance. Neptune is also famous for its intense storms, including the Great Dark Spot, an anticyclonic storm similar to Jupiter's Great Red Spot. This storm system is massive, spanning thousands of kilometers, and Neptune’s atmosphere is scattered with visible white storm clouds, adding to its dynamic weather system. Thus, Neptune is the planet known for both its striking blue color and notable storm activity in the solar system. Jupiter, on the other hand, is known for the Great Red Spot storm but is not blue—it's more brown and beige with red and white storms.
