Celestial Mechanics

For the first time in three years

Official clocks will pause for Earth's rotation

To realign with atomic time

Fluctuation is due to Earth's interaction with the Moon

Primarily tidal acceleration

This process, this effect of tidal force

Slows our planet's rotation

Angular momentum, in direct correspondence

With Earth's axial tilt is dampened

An existing kinetic energy

Within orbit is lessened

All the same, the reduction is notably fractional

Specifically, days on Earth grow 1. 4 milliseconds

Longer every one hundred years

To put that in a different perspective

It won't be for another 100, 000 years

Until each day is about one

And a half seconds longer than

As they exist today
