Pluto

Pluto is a dwarf planet located in the Kuiper Belt, a region of the solar system beyond the orbit of Neptune. It was discovered in 1930 and was initially classified as the ninth planet from the Sun. However, in 2006, the International Astronomical Union (IAU) redefined the criteria for planet classification, resulting in Pluto being reclassified as a dwarf planet.

Pluto has a highly eccentric and inclined orbit, taking approximately 248 Earth years to complete one revolution around the Sun. It has five known moons, with its largest moon being Charon, which is about half Pluto’s size. Pluto’s surface is composed of ice and rock, and it features a variety of geological structures, including mountains, valleys, and plains.

The reclassification of Pluto sparked significant debate and interest in planetary science, leading to discussions about what constitutes a planet. As of now, Pluto remains an important object of study, especially in understanding the formation and evolution of our solar system.
