The Solar System, with its diverse planets, moons, and other celestial bodies, holds many fascinating features that have intrigued scientists and the public alike. Some of these phenomena don't fit neatly into our understanding of how the Solar System should behave, leading to what we might call "anomalies." Here are ten notable anomalies:
Tilt of Uranus: Uranus is tilted so far on its axis that it essentially orbits the Sun on its side. The cause of this unusual tilt is speculated to be due to a collision with another large celestial body in the early history of the Solar System.

Pluto's Orbit: Pluto has a highly elliptical orbit that is quite tilted relative to the plane of the ecliptic (the plane in which most planets orbit). This makes its orbit intersect with Neptune’s, although a stable orbital resonance prevents collisions.

The Kuiper Belt Object (KBO) 90377 Sedna: Sedna has an extremely elongated orbit that takes it far beyond the Kuiper Belt, suggesting the influence of an unknown massive object or possibly indicating new dynamics in the outer Solar System.

The Oort Cloud Hypothesis: Though not directly observed, the Oort Cloud is theorized to exist as a vast spherical shell surrounding the Solar System, containing billions of icy objects. Its existence helps explain the source of long-period comets but remains unverified.

Mars' Two Speedy Moons: Phobos and Deimos, Mars’ moons, have peculiar orbits. Phobos orbits Mars faster than Mars rotates and is slowly spiraling inward, expected to either break apart or impact Mars in about 50 million years.

Saturn's Hexagonal Storm: At Saturn’s north pole, there is a persistent hexagonal storm system whose sides are nearly equal in length, and angles are almost perfectly 120 degrees. The exact mechanism behind this geometric shape is still under investigation.

Venus's Retrograde Rotation: Venus rotates on its axis in the opposite direction from most planets, meaning the Sun rises in the west and sets in the east. This anomaly may be due to past interactions with other bodies or atmospheric effects.

Io's Volcanic Activity: Jupiter’s moon Io is the most volcanically active body in the Solar System, driven by tidal heating from its orbital resonance with Europa and Ganymede. This level of activity was unexpected given its size and composition.

The Faint Young Sun Paradox: Early in Earth’s history, the Sun would have been much fainter than it is today, yet evidence suggests the Earth had liquid water and temperatures suitable for life. How Earth maintained such conditions is a significant puzzle.

Mercury’s Shrinking: Mercury appears to be shrinking as its interior cools. This causes the planet's surface to wrinkle like a raisin, creating cliff-like landforms known as scarps, which indicate a more complex geological history than previously thought.
