Our 24-hour day measures Earth’s rotation relative to the Sun, known as a solar day. This is slightly longer than Earth’s ...

Ever since its formation around 4.5 billion years ago, Earth's rotation has been gradually slowing down, and its days have gotten progressively longer as a result. While Earth's slowdown is not ...

For nearly a billion years, Earth’s rotation stopped slowing down. Locked in a rare cosmic balance, the planet’s day remained ...

Earth takes 24 hours to complete a full rotation in a standard day, equal to exactly 86,400 seconds. July 9 was the first of three days in which a millisecond or more could be shaved off the clock on ...

Aren’t the summer days supposed to be longer and the winter days shorter? Since when have things gone in reverse for the summertime? Since now, maybe? Starting today? Okay, here’s what’s going on.

The speed of Earth's rotation is about 1,000 miles per hour relative to its axis. Your exact speed of rotation due to Earth's spin depends on your latitude. The farther you are from the equator, the ...

Earth spun just a bit faster than usual on July 9 and is expected to do so again on July 22 and Aug. 5, according to the website TimeAndDate. Over a millisecond was reportedly shaved off the clock on ...
