Whenever planets are visible in the night sky, they always appear roughly along the same line. This path, known as the ...

The planet WASP-121b is extreme. It's a gas giant almost twice as big as Jupiter orbiting extremely close to its star–50 ...

Therefore, astronomers might expect that all of the planets in the solar system would spin in the same direction as the sun. "To look at the direction of the rotation, we always compare it to a ...

A screenshot of James’s animation “Planets and dwarf planets to scale in size, rotation speed & axial tilt in distance order from Sun”. Credit must be given to the creator. Only ...

The gas giant WASP-121b, also known as Tylos, has an atmospheric structure unlike any we have ever seen, and the fastest ...

while Kepler-62's exoplanet has a 155-day rotation period. While both planets would likely be locked into a synchronous orbit—with a permanent dayside and a perpetual nightside—the ultrafast ...

Earth Rotation Day was observed globally on Wednesday. The day celebrates the rotation of planet earth on its axis which is crucial for defining time and shape of life. Earth rotates on its axis, an ...

Over decades, the rotation of the inner core speeds up and slows down relative to the rest of the planet, affecting things such as the length of a day. Those changes in rotation are mainly due to ...

while Kepler-62's exoplanet has a 155-day rotation period. While both planets would likely be locked into a synchronous orbit -- with a permanent dayside and a perpetual nightside -- the ultrafast ...

And finally, currents of magma inside Earth's spinning, liquid core change irregularly, causing it to rotate faster or slower and altering the entire planet's rotation in the process. But now ...
