Over several decades, we can see up to 59 percent of the lunar surface because the Moon doesn’t orbit at a constant speed, and its axis is not perpendicular to its orbit. The Moon also raises ...

The Moon, on the other hand, rotates once around its own axis every 28 days, ... Speeding up the Moon’s rotation so that it spins once every 24 hours is a pretty dramatic change.

Physicists expect that this summer will be the shortest day in the history of observations.

As is the case on our own planet, the moon has its own rotation and orbit, which means only certain areas of its surface are directed towards the sun at any given time, ...

Actually, this is only mostly true. The moon's orbit around Earth isn't completely circular. During some parts of the orbit, the moon moves a bit faster than its own rotation and part of the orbit ...

But the truth is: You don't need a spacecraft to glimpse the far side of the moon. While you can only see a maximum of 50 percent of the lunar disk at any given time, bonus smidges of its surface ...

Fossilized corals, lasers beamed at a receding moon, Chinese artifacts, and other evidence have revealed that over the ages the length of time it takes Earth to spin once on its axis has increased ...
