Earth's speed of rotation is slowing!
In a study conducted by the Columbia and Wisconsin Universities, it was discovered that Earth had completed its turn around its axis in 18.7 hours, 1.4 billion years ago.

A study of Earth's relation to the Moon and other planets has shown that it lasted 18.7 hours a day on Earth 1.4 billion years ago.

A survey of scientists from the Lamont-Doherty World Observatory and University of Wisconsin at Columbia University used a statistical method to illuminate the past of the Earth, reconstruct the history of the Solar System, and correlate astronomical theory with geologic observations to understand climate change in prehistoric times.

The survey, published in the journal "Proceedings of the National Academy of Sciences," estimates that 1.4 billion years ago, the distance between Earth and Moon was closer to the present, or about 341 thousand kilometers. The research was funded by the US National Science Foundation.
