The planet known for its distinctive blue color is Neptune. This striking hue is due to the presence of methane in its atmosphere, which absorbs red light and reflects blue light back into space. Neptune is an ice giant, composed mainly of hydrogen and helium, along with a significant amount of water, ammonia, and methane ices. Its vibrant blue color, combined with its active weather patterns, makes it one of the most visually intriguing planets in our solar system. Notably, Neptune also boasts dynamic atmospheric features, including storms and high-speed winds, contributing to its unique appearance.
