💡The exploration of Pluto challenges our understanding of the solar system, pushing us to redefine the definition of a planet.

How was Pluto discovered?

—The discovery of Pluto was the result of a decades-long search for Planet X, a hypothetical ninth planet. Percival Lowell, founder of the Flagstaff Observatory, led the search based on observations of Uranus and Neptune's orbits.

Why was Pluto downgraded to a dwarf planet?

—Pluto was downgraded to a dwarf planet by the International Astronomical Union (IAU) due to its inability to clear its orbit of other objects. This criterion led to the reclassification of Pluto and the establishment of a new definition for planets.

What did the New Horizons mission reveal about Pluto?

—The New Horizons mission provided high-definition images of Pluto, uncovering its complex geological features, including towering mountains, ridged terrain, and a heart-shaped plain known as Sputnik Planitia. These images revolutionized our understanding of this distant world.

What is Sputnik Planitia?

—Sputnik Planitia is a heart-shaped plain located in the western lobe of Pluto's heart. It is made of frozen nitrogen, methane, and carbon monoxide. This region captivates scientists with its unique attributes and atmospheric phenomena.

How has the exploration of Pluto challenged our understanding of the solar system?

—The exploration of Pluto has forced scientists to reconsider the definitions and classifications of celestial bodies. The discovery of numerous dwarf planets in the Kuiper Belt and the complexities observed on Pluto demonstrate the diversity and intricacy of our solar system.
