A year of pluto-"dwarf planet"

Pluto is a relatively small celestial object in our solar system, situated beyond the orbit of Neptune. It was formerly considered the ninth planet but was reclassified as a "dwarf planet" in 2006 due to its characteristics differing from the traditional definition of a planet. Pluto has a diameter of approximately 2,377 kilometers (1,477 miles) and is composed primarily of rock and ice. It has a unique reddish-brown coloration on its surface, possibly due to the presence of complex organic compounds.

Pluto has a highly elliptical orbit, taking about 248 Earth years to complete a single orbit around the Sun. Its orbit is inclined and tilted relative to the plane of the solar system, causing its distance from the Sun to vary significantly during its orbit. Pluto has five known moons: Charon, Styx, Nix, Kerberos, and Hydra. The largest moon, Charon, is unusually large compared to Pluto, leading some scientists to consider the Pluto-Charon system as a binary planet.

Pluto's distant location and small size make it a challenging object to study in detail, but advancements in space exploration have provided valuable insights into its composition and characteristics. The New Horizons spacecraft conducted a flyby of Pluto in 2015, capturing close-up images and data that revealed a diverse and complex surface with features such as ice mountains, nitrogen ice plains, and a possible subsurface ocean.
