Why the speed of the Earth this Friday will be 7,000 km / h slower than in January – Business Season

As Kepler's law says, when planets are close to the Sun, they move more. As pointed out one of Kepler's so-called laws on planetary movements, formulated by the German astronomer and mathematician Johannes Kepler in the 17th century, when the planets are close to the sun they move more as fast as when they are far away

The translational orbital velocity will be 103,536 kilometers per hour, or more than 7,000 kilometers less per hour than the speed of perihelion

The seasons of the year. year
The reductions or increase in the speed of the Earth in the road around the Sun have nothing to do with the changes in temperature and climate of the seasons.

"The seasons come by the inclination of the axis of rotation of the Earth relative to the plane of the orbit around the Sun, which we call" ecliptic ", said Rodríguez Eugenio

"This axis is tilted at about 23.5 degrees, so that When we are in the northern hemisphere in summer, the north axis, or north pole of the Earth, is pointed in winter, our north pole is pointed in the opposite direction – not exactly the opposite , about 23.5 degrees, but it is pointing in the opposite direction to the Sun. "

More water in the summer of the northern hemisphere coincides with the aphelion," but we get more solar radiation here in the hemisphere North because the sun is higher on the horizon and we have more hours of sunshine ", says Astrophysics

.In the southern hemisphere, on the other hand, the summer coincides with perihelion

"This could make us think that in the southern hemisphere the temperature rises more than in the north in summer because, besides the slope, the earth is also closer"

In the southern hemisphere, there is more water than in the northern hemisphere, which means that the temperature does not increase (19659003). The answer is that "in the southern hemisphere, there is a greater amount of water and that does not increase the temperature so much," she says.

which is due to the fact that the earth warms more easily than water, and that the southern hemisphere has a greater proportion of its territory covered with water, the l '. Excess energy is absorbed by it. "

summer, both in the southern hemisphere and in the north, the temperature is about the same," Astrophysics explained
