Without the Moon, the Earth would rotate

Day length and Moon
The absence of the moon would also affect the Earth's rotation on its axis. The moon's gravity increases the length of a day by about two milliseconds every 100 years. Although if this increase were to stop tomorrow, it wouldn't be very noticeable on our human time scale.



But if the Moon had disappeared billions of years ago, the Earth's rotation would be completely different today.

very quickly, and it is not easy to imagine what life on the saudi arabia number data planet was like.

In the beginning, our planet had a four-hour rotation, which the Moon slowly and persistently slowed down to the 24-hour day we are so familiar with. Without the Moon's presence all these years, we would still be rotating much faster - and feeling even more like there were not enough hours in the day.

“Everything we know about the seasons would be completely out of place,” says Paul Sutter, an astrophysicist at the Flatiron Institute. At a certain angle, “in some places on the planet the Sun would be almost never visible, while in others it would hang overhead for months on end.”

However, the change in the Earth's tilt will happen gradually, so we won't notice it immediately or, more likely, even during our lifetimes. But animals that have evolved over millions of years to live in sync with the seasons may have a hard time adapting, even over what seems like a long period of time to us.

Tides help mix cold Arctic waters with warmer waters in the tropics. This balances temperatures and stabilizes climate around the world. Without the Moon, weather forecasting would be virtually impossible. The average difference between the hottest and coldest places on Earth can grow to life-threatening extremes.

But all of this pales in comparison to the biggest changes we're about to see over the next few millennia. Right now, the Earth is tilted 23.5° on its axis, largely due to the Moon's gravity. If the Moon were to disappear, the Earth's axis would wobble by anywhere from 10° to 45°.
