Why will 2021 be the shortest year in decades according to science?

If lately you have felt that time is running too fast and that 2021 It is flying by, you are not crazy. It’s true: the Earth is accelerating its translation causing this year to be the shortest in decades.

In research published in Time and Date magazine, astrophysicist Graham Jones of the University of London, revealed that for a couple of years it has been known that the 2020 and the 2021 they would be two of the shortest years on record.

This had not happened since 2005, when the shortest day was recorded on July 5, since the Earth’s rotation lasted 1.0516 milliseconds less, but why is this?

Why will 2021 be an even shorter year?

The Earth rotates on itself once every 86,400 seconds, which is equivalent to 24 hours or one day on the solar scale. However, the rotation of the planet is not exact and scientists, with the help of atomic clocks, which are the most precise that exist, determined that the solar day can vary a few milliseconds.

In this way it was announced that in 2020 the Earth broke its speed record on its own axis 28 times throughout the year. In the end, it had a translation of 1.4602 milliseconds less than usual. Something that will be repeated again in 2021, a year that will be even shorter than the previous one.

The speed with which the Earth rotates depends on many factors, such as the movement of its own core, the oceans, the atmosphere, gravity and external elements, causing the solar day to last 0.2 milliseconds less than normal on a daily basis.

“How time flies…”
