The Earth revolves around the Sun, describing an elliptical orbit of 930 million kilometers, at an average speed of 107,280 kilometers per hour .
However, this translation speed varies , increasing to a maximum at perihelion (the shortest distance to the Sun) with 110,700 kilometers per hour, and decreasing to a minimum at aphelion, with 103,536. A difference of 7,000 kilometers per hour .
The orbit that the Earth describes involves traveling its entire distance in 365 days and almost 6 hours, hence every four years a leap is counted. Precisely, this 2020 is leap .
However, the orbital speed of a planet will be lower, at a greater distance from the Sun, and at shorter distances the orbital speed will be greater. The mean distance from the Sun is on average 150 million kilometers. At aphelion it reaches 152.09 million kilometers and at perihelion it drops to 147.10 million kilometers away .
The Earth will cross the furthest point from the Sun in its orbit in 2020 on July 4, an astronomical milestone known as aphelion, which takes place every year between July 2 and 7.
In turn, the Sun is not standing still. It is launched at 790,000 kilometers per hour towards the center of the Milky Way. Thus, the Sun (and all the planets that surround it, the Solar System) make a complete turn on the merry-go-round of the Milky Way in 200 million years. Currently a quarter turn from the age of the dinosaurs has already been completed.
