by Planet Earth will run a little faster this summer on three separate days, starting on July 9. This will result technically up to shorter days, but the change will be so minuscule that you will not even notice it.
Different milliseconds will be shaved of the 24 hours needed to complete the earth a full rotation – we talk less time than an instant.
Why does the rotation speed of the earth change?
Planet Earth is our timekeeper, but it is not perfect.
It takes our planet 24 hours – one day – to complete one full rotation on its axis, which falls apart to 86,400 seconds. But the rotation of the earth could change every day with a millisecond (.001 seconds) or two.
The lane of the moon can have an effect on how quickly the earth rotates. “Our planet runs faster when the position of the moon is far north or south of the Equator equator,” said TimeAnddate.com.
“Earthquakes, volcanoes, tidal forces, underground geology and many other mechanisms can cause the rotation of the planet to delay or accelerate, and those micro-adjustments can trace over time,” the popular mechanics reported.
The earthquake of 8.9 Magnitude that hit Japan accelerated the rotation of the earth in 2011, which reduced the length of the standard 24-hour day with 1.8 microseconds (0.0018 milliseconds).
These small daily fluctuations in the spider speed of the earth were measured in the 1950s with atomic clocks. Each number above or below the standard 86,400 seconds is mentioned the length of the day (LOD).
The shortest registered day was on July 5, 2024, when the earth completed its full rotation 1.66 milliseconds faster than the standard 86,400 seconds.
When will this happen?
There are three days this summer when the moon will be around the farthest distance of the Earn’s Equer, resulting in a tiny increase in the spider speed of the earth. The following are predictions of scientists:
-
July 9: The day is shortened by 1.30 milliseconds
-
July 22: Earth loses 1.38 milliseconds of the day
-
August 5: The day is shortened by 1.51 milliseconds
Wait – Is there not another day that is considered the shortest of the year?
What feels like the shortest day of the year in the northern hemisphere is known as the winter solstice when the earth is taken away from the sun. This results in the least amount of daylight hours throughout the year and occurs in mid -December.
Will the earth always have 24 hours a day?
There were not always 24 hours a day. Researchers believe that during the Jura period only 23 hours took the earth to make a complete rotation around his axis. Scientists have discovered that the length of a day on earth increases every century by around 1.7 milliseconds. After a while that comes up. Experts think that there will be 200 million years now that 25 hours will be on a full day.
