Earth to Spin Faster on July 22, to See 2nd Shortest Day of the Year
In a rare phenomenon, the Earth is expected to spin faster than usual on July 22, resulting in the second-shortest day of the year. According to NASA data, the planet will complete a full rotation around the Sun in a mere 23 hours and 59.66 minutes, which is 1.34 milliseconds less than the standard 24 hours.
This extraordinary event will be the second-shortest day of 2025, following July 10, which clocked in at 1.36 milliseconds short. The shortest day ever recorded was on July 5, 2024, with a difference of 1.66 milliseconds.
The slight acceleration in the Earth’s rotation is a result of various celestial and atmospheric factors, including changes in the planet’s angular momentum, atmospheric circulation patterns, and even the gravitational pull of other celestial bodies.
The phenomenon is not uncommon, as the Earth’s rotation can vary by up to 1.78 milliseconds per day due to the planet’s slightly ellipsoidal shape and the gravitational pull of the Moon. However, events like this one, where the difference is significant, are relatively rare and often occur due to unusual atmospheric and celestial conditions.
To put this into perspective, a normal day on Earth typically lasts 24 hours, with the planet taking approximately 86,164.1 seconds to complete one full rotation around the Sun. On July 22, the Earth will complete this rotation in 86,162.7 seconds, resulting in a shorter day than usual.
This phenomenon is not only fascinating from a scientific perspective but also has practical implications for our daily lives. For instance, the accelerated rotation of the Earth will lead to slightly faster rotational speeds for objects on the planet’s surface, including rocks, buildings, and even the human body.
The effects of this accelerated rotation will be relatively small and may not have a significant impact on our daily lives. However, it’s a fascinating reminder of the complex and dynamic nature of our planet and its relationship with the celestial bodies that surround it.
As we prepare to experience the second-shortest day of the year, it’s a great opportunity to reflect on the incredible phenomena that occur on our planet. From the tides to the seasons, the Earth’s rotation is just one of the many fascinating aspects of our world that shape our daily lives.
