How much are we going? Today is the fastest day on Earth in the year



This January 3, the Earth is located in the perihelion, closer to the Sun in its annual orbit. It produces maximum orbital speed, accelerating 3,420 kilometers per hour above the average.

The Earth revolves around the Sun, describing an elliptical orbit of 930 million kilometers, with an average speed of 107,280 kilometers per hour, which means traveling at a distance of 365 days and almost 6 hours, so every four years the jump counts.

But according to Kepler's second law, the speed of translation varies, increasing to the maximum in the perihelion – the smallest distance to the Sun – 110,700 kilometers per hour, and the reduction to be minimal in the affliction (reaching July 5), 103,536 kilometers per hour, more than 7,000 kilometers per hour difference.

The perihelion of 2019 occurred at 5:20 pm UTC on January 3 (2.20 in Argentina in the morning), with a distance of just over 147 million kilometers. The 2019 report will be on July 5, about 5 million kilometers.

Kepler realized that the line connecting the planets and the sun covers the same area at the same time. This means that when the planets are close to the Sun in their orbit, they move faster than when they are farther away.

Thus, the orbital velocity of the planet will be smaller, at a greater distance from the Sun, and at shorter distances, the orbital velocity will be higher. The average distance of the Sun is an average of 150 million kilometers. In the affliction it reaches 152.09 million kilometers, and in the perihelion decreases to 147.10 million kilometers.
