Slowing of Earth’s Spin Revealed in Ancient Astronomers’ Tablets
The work of ancient astronomers reveals that the Earth’s spin is slowing down — though not as much as scientists believed.
Each century, the length of the solar day, or the time it takes the planetto do a full rotation, grows by 1.8 milliseconds, according to a new study using astronomical observations going back to 750 B.C. Researchers have known that the planet’s rotation is slowing because of friction caused by the tides, as water that’s being tugged on by the moon’s gravity sloshes against the solid Earth. However, measurements of this tidal effect suggest that the planet should be slowing in its rotation by 2.3 milliseconds per century, slightly more than the new research finds.
The difference between 2.3 milliseconds and 1.8 milliseconds over a century may seem trivial, said study researcher Leslie Morrison, who worked at the Royal Greenwich Observatory for nearly 40 years. But those fractions of milliseconds are important for understanding the ways that the Earth has changed shape since the end of the last ice age, about 12,000 years ago, Morrison told Live Science.
