Pluto, once considered the ninth planet in our solar system, is now classified as a dwarf planet. It resides in the Kuiper Belt, a region beyond Neptune filled with icy objects. Pluto is relatively small, with a diameter of about 1,473 miles (2,377 kilometers), which is roughly two-thirds the size of Earth's moon. It was discovered in 1930 by Clyde Tombaugh. One intriguing fact about Pluto is its peculiar orbit, which is highly elliptical and inclined compared to the other planets in our solar system. This orbit causes Pluto to cross Neptune's path at times, making it the eighth-most distant planet from the Sun during those periods. Pluto also has a thin atmosphere primarily composed of nitrogen, and its surface is covered in icy plains and mountains. In 2015, NASA's New Horizons spacecraft provided the first close-up images and data about Pluto, revealing its diverse landscape and complex geological features, further fueling our fascination with this distant world.
