Despite once being considered the ninth planet in our solar system, Pluto was reclassified as a dwarf planet in 2006 by the International Astronomical Union (IAU).
Pluto is incredibly cold, with surface temperatures dropping to about -240 degrees Celsius.
A distinctive heart-shaped region on Pluto’s surface was captured by NASA’s New Horizons spacecraft during its historic flyby in 2015.
Pluto has a thin and tenuous atmosphere primarily composed of nitrogen, methane, and carbon monoxide.
Pluto has five known moons. Charon, the largest moon, is so large in comparison to Pluto that the two bodies are often considered a binary system.
Pluto has a unique orbit that is more tilted and elliptical compared to other planets in our solar system.
Some regions on Pluto’s surface appear to contain vast plains of frozen methane.
Pluto is situated in the Kuiper Belt, a region beyond Neptune. Its distance from Earth varies from about 4.67 to 7.4 billion miles.
