Earth will spin faster this January 4 and here’s why

it’s january 4th, Earth will be at perihelion closest to the Sun in its annual orbit. It produces maximum orbital speedAverage speed of 3,420 kmph.

AleThe Earth revolves around the Sundescribing an elliptical orbit of 930 million kilometers at an average speed of 107,280 kilometers per hour, which means traveling the distance 365 days and about 6 hours, so there is a leap year every four years.

But, according to Kepler’s second law, this translational speed varies, until it increases with a maximum at perihelion (shortest distance from the Sun) at 110,700 kilometers per hour, and a minimum at aphelion with 103,536 kilometers per hour. It happens. , In addition to over 7,000 kmph.

According to Earth and Sky, the subsolar of 2023 will be At 3:00 p.m. (Central Mexico Time), this Wednesday, January 4th, with a distance of only 147 million kilometers. In 2023, the aphelion will be about 5 million kilometers away on July 6.

Kepler realized that the line connecting the planets and the Sun covered the same area in the same amount of time. it means that When planets are closer to the Sun in their orbit, they move faster than when they are farther away.

Thus, a planet will have a lower orbital speed at a greater distance from the Sun, and a higher orbital speed at a smaller distance. The average distance from the Sun is an average of 150 million kilometers. It reaches up to 152.09 million km on the apseor and it decreases to 147.10 million km on the apse.
