Today, Earth is moving slower than normal and that is the reason – Astronomy

Today, July 6, the Earth will move more slowly than the rest of the year, about 3,600 kilometers per hour less than its maximum speed.

It is a phenomenon known as Afelio a word of Greek origin meaning 'Away from the Sun'. It is precisely when our planet is living today, at least the distance will be what allows it the most

During the aphelion the Earth is about 152 million kilometers from Sun unlike the perihelion phenomenon, which is when, the distance is reduced to about 147 million kilometers. According to the proximity of Earth with Sol and Luna the motion of the Earth will still depend

Recall that this distance varies because The orbit of the Earth around Sun is not a perfect circumference, as we sometimes draw it at school, but it is elliptical.

This change is explained by Kepler's second law where he explains that when the planets are close to the Sun in their orbit, they move faster than when they are far away.

Tierra al Sol will be reached this Friday at 17:46 GMT, while it is 152 095 566 kilometers date at which the speed of translation of the planet around the sun will be only 105 444 km / h, or about 3,600 km / h less than its perihelion speed. [1 9659002] The aphelion takes place every year between the 2nd and the 7th of July. Perihelion occurred this year on January 3rd.

Does the distance between the Sun and the Earth influence the change of seasons?

In the northern hemisphere it is summer, while in the south it is winter. However, the greater or lesser distance to the Sun during one or the other of the two phenomena, aphelion or perihelion, has no relation to temperature variations during the seasons.

"The seasons are produced by the tilt of the axis of rotation of the Earth compared to the plane that it describes around Sun what we call the ecliptic ", Rodríguez Eugenio pointed out the BBC

" This axis is inclined at about 23.5 degrees and so when we are in the summer of l & # 39; northern hemisphere, the north axis, ie the north pole of the Earth points further towards the direction of Sun . "

" Instead in the winter, our North Pole points in the opposite direction, this is not exactly the opposite because it is about 23.5 degrees, but it points in the opposite direction to "he explained.
