9 July 2025, ie today, the day will end 1.59 ml second ago as compared to normal days. Which can be considered the smallest day in history. Earlier on 5 July 2024, Prithvi finished its round 1.66 ml second ago. The Earth finishes a complete round in 24 hours.
According to the New York Post report, according to the International Earth rotation (circulation) and reference system service (IERS), on July 22 and August 5, the days of August 22 and August 5 can remain 1.3 to 1.51 milliseconds smaller than normal days.
The New York Post quoted Duncan Agnue, the Geofigist Duncan Agnue of the Scripts Institution of Oceanography, University of California, San Diego- this is an unprecedented situation and also a big thing.
He said- this is not a big change in the circle of the earth, which will cause someone else to become a disaster or something, but it is worth noting.
According to Live Science, the Moon is affecting the Earth’s rotation. The earth is rotating slightly sharply. Iers supervise global time keeping.
What is the speed of the Earth’s rotation?
One day on Earth means- the Earth is to make a complete round on its axis (Axis). It takes about 86400 seconds to complete a round i.e. about 24 hours.
The speed of the Earth’s rotation is not always the same. It affects many things, such as the position of the sun and the moon, changes in the magnetic field of the earth, uneven distribution of mass inside and out of the Earth, including melting of snow or changing sea levels.
Earlier Earth used to complete the round in 19 hours
Scientists believe that 1 to 2 billion years ago, the Earth used to roam in just 19 hours a day. This was because at that time the Moon was very close to the Earth and its gravity had a lot of effect.
This stretch of the moon rotated the earth rapidly. Gradually, the Moon walked away from the Earth, which weakened its grip and the earth’s speed also slowed down. Because of this, the days started getting longer, meaning the time taken in a day started increasing.
In recent years, scientists noticed that this pace has started growing a bit again, which is a surprising thing. For example- In 2020, scientists noticed that the Earth was moving faster than before, the faster it never turned around before 1970 (since the exact measure has started).
