This January 4, 2022, the Earth will reach perihelion, hence its maximum speed around the sun.
At each beginning of the year, the Earth’s elliptical orbit reaches its point Very close approach to the sun, Called Perihelion.
When the Earth is in perihelion, its orbital velocity Accelerate to maximum; The opposite happens when we are on the Abelian and our planet is moving at a minimum speed.
This Tuesday, January 4, at 00:52 (GMT -6), our planet a The minimum distance from the sun is 147 million kilometers, Enough, instead of traveling at an average speed of 107,280 kilometers per hour, it accelerates to a maximum speed of 110,700 kilometers per hour.
This increase in ground speed, although not visible to the inhabitants during the perihelion, The amount of sunlight reflected on Earth is 7% higher than that falling on the abyss. This event is one of the current seasons (Burial Winter and Australian Summer) 4.7 days short duration During the Abyssinian period, rather than the seasons that occur in July.
However, the effects of perihelion on life on Earth are minimal and, instead, Major weather variables are due to the seasons of the year, Caused by an inclination of 23.5º on the axis of rotation of the earth.
Therefore, the maximum and minimum distances between the Earth and the Sun are not related to the Earth’s temperature, which is most evident in the countries of the Northern Hemisphere, where winter causes the lowest temperatures of the year. In the sun it is very low, while in summer the heat waves coincide with the abyss.
In 1609, Johannes Kepler Instead of perfect circles, the orbits of the planets around the sun are elliptical, which was the first to suggest that they have our nearest star at one of their centers. From systematic observations and calculations, Kepler outlined three basic laws that would be useful to further explain. The motion of the planets and the speed around their orbits.
From the concept of elliptical orbits, it was possible to identify the nearest point (perihelion) and the farthest point from the Sun (Abelian). Kepler also proposed it The areas where the planets rotate in their orbits pass at equal intervals, So that their orbital speeds are closer to their star.
Although this effect is minimal due to its low eccentricity on Earth, this phenomenon is still dramatic for such objects Pluto, Its longest orbit around the sun in a short period of time, which translates to 247 years Closer to the Sun than Neptune.
