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:
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.Show More
