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 ...

While both planets would likely be locked into a synchronous orbit -- with a permanent dayside and a perpetual nightside -- the ultrafast white dwarf planet's rotation stretches out the cloud ...

Explore seven factual aspects of Jupiter, including its size, moons, rotation, atmosphere, rings, formation, and magnetic field based on NASA findings.

Astronomers have found that the rotational profile of a nearby star, V889 Herculis, differs considerably from that of the Sun. The observation provides insights into the fundamental stellar ...

One of the interesting facts about our Solar System is how fast different planets spin on their axis. Earth takes about 24 hours to make a full rotation, but some planets spin much quicker, making ...
