Pluto, once considered the ninth planet in our solar system, is now classified as a dwarf planet. It is located in the Kuiper Belt, a region of icy bodies beyond Neptune. Pluto has a diameter of about 2,377 kilometers, making it much smaller than Earth's Moon. Despite its small size, Pluto has a complex surface with mountains, valleys, and plains, and its atmosphere, primarily composed of nitrogen, can freeze and thaw as the planet moves closer to and farther from the Sun. In 2015, NASA’s New Horizons mission provided the first close-up images of Pluto, revealing surprising details about its geology and atmosphere. Although no longer a planet, Pluto continues to fascinate scientists and astronomers.
