On July 5, 2024, the Earth completed a rotation in 1.66 milliseconds less than 86,400 seconds. This broke the record for the shortest day measured in the atomic era. The Earth's rotation speed is influenced by factors such as the Moon's gravity and seasonal mass changes. However, in recent years, the Earth's rotation speed has been slightly increasing.
This increase in the Earth's rotation speed is surprising scientists. Because, factors such as the Moon's gravity and seasonal mass changes would be expected to slow down the Earth's rotation speed. However, in recent years, the Earth's rotation speed has been slightly increasing. The reason for this increase is still being researched by scientists.
This increase in the Earth's rotation speed has global significance. Because, this increase broke the record for the shortest day on Earth. Additionally, this increase helps scientists better understand the Earth's rotation speed.
