How much do we go? Today is the fastest day on earth in the year



This January 3, the Earth in Perihelion is located, closer to the Sun in its annual cycle. It provides the maximum speed of rotation that accelerates the average of 3,420 kilometers per hour.

The Earth is about the sun, which describes an elliptical circuit of 930 million kilometers, with an average speed of 107,280 kilometers per hour, which means driving the distance for 365 days and nearly 6 hours, so every four years it is a counting year.

But according to Kepler's second law, this translation rate varies and is increased to be maximum in the perihelion – the smallest distance to the sun – by 110,700 kilometers per hour and reduced to a minimum in aphelion (reaching July 5), with 103,536 kilometers per hour, more than 7,000 kilometers in hours difference.

Perihelion of 2019 took place at. 05.20 UTC on January 3 (at 20.20 in the morning in Argentina) with a distance of just over 147 million kilometers. Aphelion in 2019 will be July 5, about 5 million kilometers away.

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 circuits, they move faster than when they are farther away.

Thus, a planet's orbital velocity will be lower, at a greater distance from the sun, and at shorter distances, the rotational speed will be higher. The average distance of the sun is 150 million kilometers. In the aphelion it reaches 152.09 million kilometers and in the perihelion it falls to 147.10 million kilometers away.
