Linked from

The 28 pages that link to Pluto, each with the reason it gives.

• International Astronomical UnionRelated: Its reclassification made the Union’s planet definition globally consequential.

• Operation OverlordRelated: Its pipelines helped supply Allied forces advancing after the Normandy landings.

• NeptuneCompared with: Its reclassification as a dwarf planet contrasts with Neptune’s status as a planet.

• Kuiper beltBroader topic: It is the belt's best-known member and a world explored at close range.

• Solar SystemBroader topic: Its reclassification shows how the definition of planet separates major worlds from other round bodies.

• Axial tiltBroader topic: Its large axial tilt and eccentric orbit create unusual seasonal patterns.

• Dwarf planetBroader topic: Its reclassification made the new dwarf-planet category widely known.

• Normandy landingsRelated: It helped supply the advancing forces after the beachhead was established.

• CeresCompared with: Pluto shares Ceres’s dwarf-planet classification but occupies a distant, icy outer region.

• HeliosphereCompared with: Its orbit lies deep inside the heliosphere, far short of the heliopause.

• New HorizonsRelated: New Horizons made the first close exploration of Pluto, revealing its varied geology and atmosphere.

• Gravitational perturbationRelated: Neptune's perturbations help maintain Pluto's resonant orbit and protect it from close encounters.

• Mean-motion resonanceBroader topic: Its 3:2 resonance with Neptune protects it from close encounters despite orbit crossing.

• Trans-Neptunian objectBroader topic: Pluto is the largest known trans-Neptunian object and the first discovered.

• Minor planetCompared with: Pluto illustrates why a large trans-Neptunian body can be classified as a dwarf planet rather than a minor planet.

• CharonRelated: Charon is Pluto’s largest moon, and the two bodies are mutually tidally locked.

• Clyde TombaughBroader topic: It is the celestial body Tombaugh discovered and the focus of his lasting fame.

• Percival LowellBroader topic: The search inspired by Lowell led to Pluto’s discovery, although Pluto did not account for his predicted orbital discrepancies.

• Stellar occultationBroader topic: Occultations have measured Pluto's size and probed its changing atmosphere.

• HaumeaCompared with: Pluto is the best-known Kuiper belt dwarf planet, but its shape and rotation differ from Haumea’s.

• Atmosphere of PlutoNarrower topic: Its gravity, surface, and orbit together shape the atmosphere’s behavior.

• ArrokothRelated: New Horizons studied Pluto before continuing onward to Arrokoth.

• IAU definition of planetBroader topic: Pluto is nearly round and orbits the Sun, but has not cleared its orbital neighborhood.

• Moons of PlutoRelated: Its gravity and shared history with Charon anchor the orbits and origins of all five moons.

• Discovery and exploration of the Solar SystemBroader topic: Its discovery prompted a long debate about the boundaries and categories of the planetary system.

• Jane LuuRelated: The discovery came beyond Pluto, once thought to mark the Solar System's outer edge.

• Naoki UrasawaBroader topic: The series demonstrates Urasawa’s approach to suspense and moral questions through adaptation.

• Planets beyond NeptuneRelated: It was once treated as the predicted Planet X, though its mass cannot explain the original anomalies.
