Uranus: Sideways Rotation Mystery — Reading Comprehension

The planet Uranus is the seventh planet from the Sun in our solar system. Most planets spin, or rotate, around an imaginary line called an axis. For Earth, this axis is tilted just a little, making day and night. But Uranus is unique. Its axis is tilted by about 98 degrees, meaning it almost rolls around the Sun on its side!

The rotation of Uranus is very different from other planets. While Earth rotates upright, Uranus spins like a ball rolling on the ground. Scientists believe a huge space object, maybe as big as Earth, crashed into Uranus long ago. This giant impact knocked Uranus over, causing its strange sideways rotation. This tilt changes how sunlight reaches different parts of Uranus and creates unusual seasons that last over 20 years each.

Uranus also has faint rings and at least 27 known moons. Because of its tilt, the rings and moons circle Uranus in a different way than around other planets. The sideways spin also causes strong winds and odd weather patterns in Uranus's blue-green atmosphere, made of hydrogen, helium, and methane. The methane gives Uranus its special color.

Studying Uranus helps scientists learn about space collisions and how planets can change over time. Understanding the orbit and rotation of planets also helps us predict seasons, weather, and even plan for space travel. The mystery of Uranus’s sideways spin shows how exciting and surprising our solar system can be!

Interesting Fact: One day on Uranus lasts about 17 hours, even though its year—one trip around the Sun—takes 84 Earth years!
