Discover the only planet in our solar system that rotates clockwise. Learn why this 'rebel' planet spins backwards, how a ...

A planet's year length depends on its distance from the Sun. Planets closer to the Sun have shorter years. A planet's rotation speed is unrelated to its year length. Planets' orbital speeds vary ...

Jupiter boasts the shortest day in our solar system, completing a rotation in just under 10 hours. This rapid spin, a result of its immense size, gaseous composition, and retained angular momentum ...

A planet's north pole is defined by its position relative to the solar system's invariable plane. The invariable plane is a fixed reference point perpendicular to the solar system's rotation. A planet ...

Tracking the rotation speed of solid planets, like the Earth and Mars, is a relatively simple task: Just measure the time it takes for a surface feature to roll into view again. But giant gas planets ...

These interactions lead to changes in a planet's rotation and temperature, accelerating one and raising the other. Scientists can observe these changes, and the authors have developed a new approach ...
