The National Astronomical Observatory reported that this January 2 the planet Earth will reach the highest speed it will have in the whole year, As it will record a speed of 110,700 kilometers per hour (30.75 kilometers per second).
The phenomenon is known by the name “Periheli,” and that’s when the Earth is closer than ever to the Sun., About 147,093,051 miles away.
The Earth revolves around the Sun with an elliptical orbit of 930 million kilometers, at an average speed of 107,280 kilometers per hour, which means traveling the distance in 365 days and almost six hours, for this reason every four years. 1 transfer is counted.
The opposite of “perihelion” is “aphelion,” which is when we are farthest from the sun. This phenomenon will happen on July 5, and the distance between the Earth and the Sun will be 152,100,375 kilometers.
According to experts, the dates of these phenomena is not fixed, As it varies from year to year according to the sequence of years according to the calendar (some of transfer, others not) with the duration of each orbit of the Earth around the Sun (duration known as year tropics).
Why is it colder if we are closer to the Sun?
This is the question we all ask ourselves after hearing the news; however, in reality this depends on the inclination of the Earth’s axis of rotation.
Therefore, the northern hemisphere is closer to the Sun in winter, which causes their winters to be less cold than those of the southern hemisphere, therefore, summers are less hot in the northern hemisphere.
