TimeAndDate.com reports that our planet has broken a record, completing one revolution more quickly than any other time in the history of such tracking. On Wednesday, June 29, the Earth completed one revolution on its axis. This was 1.59 milliseconds quicker than 24 hours.
In the 1960s, atomic clocks started to track data with this level of accuracy. Scientists have often observed that the Earth’s rotation is slowing down. To compensate for the slow rotation, the International Earth Rotation Service has begun to add leap seconds to its calculations (the last time this happened was December 31, 2016).
Atomic clocks have shown that Earth’s orbit is increasing over the last few years. Scientists recorded the 28 shortest days in 2020 since 1960. This trend didn’t continue last year: The shortest day in 2021 was actually longer than the one before.
Our planet’s fastest rotation occurred on June 29, 2022. The day’s fastest rotation was then completed in 1.50 milliseconds under 24 hours on July 26, 2022. The previous record was set July 19, 2020 when Earth’s orbit took 1.4602 milliseconds more than 24 hours.
Because the Earth’s orbit accelerates, the atomic clocks used by GPS satellites don’t account for this change in Earth’s spin. The Earth will rotate faster and reach the same place a little sooner if it does so. A half-millisecond equals 26 centimeters at equator. This could theoretically cause the GPS to be inaccurate, according to the source.
