In 200 million years the day will have 25 hours – The Moon is moving away from Earth

It is estimated that in about 200 million years, as the day will grow steadily, the 24-hour period will be over 25 hours. So, if anyone wishes the day to last longer, his wish will take place in the distant future – though he will not live to enjoy it.

The change during the day is mainly due to the fact that, as the years go by, the Moon is moving away from our planet. Over the last 1.4 billion years it has been evacuated around 44,000 kilometers. This makes the Earth spin slowly around its axis, which lengthens during the day (as the day is only the duration of a full Earth rotation).

Today, the moon is moving away from the Earth at a rate of 3.82 cm per year, making the day every year almost 1 / 75,000 milliseconds. The researchers, headed by geoscience professor Steven Meyers, of the University of Wisconsin-Madison , published in the journal of the National Academy of Sciences of the United States (PNAS).

The new study creates a model for the Earth-Moon relationship lost in the depths of time, developing a statistical method that links astronomical and geological history. Scientists believe that the Earth’s removal of the moon will stop at some point in the very distant future, when the moon will stabilize at a certain distance from our planet.
