Our planet will traverse this July 6th its farthest point from the Sun in its orbit, an astronomical landmark known as the aphelion, which takes place every year between July 2nd and July 7th.
The exact moment of greater separation will take place at 17:46 (GMT), when the Earth and the Sun will be 152 million 95 thousand 566 kilometers, according to information from Earth Sky.
Based on Kepler's second law, this distance also translates into the lowest orbital translation speed, with 103 thousand 536 kilometers per hour, more than 7 thousand kilometers per hour more slowly than in perihelion, recorded last 3 January 19
This happens because in its movement around the Sun, the Earth does not take a perfect but elliptical circular path.
Kepler realized that the line that connects the planets and the Sun covers an area in the same amount of time. This means that when the planets are close to the Sun in their orbit, they move faster than when they are farther apart. Thus, the orbital velocity of a planet will be lower at a greater distance from the Sun, and at lower distances the orbital velocity will be higher.
The fact that the Earth is further away from the Sun in the middle of summer has nothing to do with seasonal warmth. Northern hemisphere or winter in the southern hemisphere. This is the greatest number of hours of sunshine, due to the inclination of the Earth's axis, which governs the rise or fall of seasonal temperatures.
