Earth will reach perihelion on January 4 at 10:00 a.m. (CST), meaning it will be at its closest point to the Sun in 2023, so it will have a higher orbital speed, with a speed of 3,1,420 kilometers per hour. Hour above average.
Earth’s orbit around the Sun is not a circle but an ellipse, so it makes sense that the earth would have closest and farthest points from the sun every year. By 2023, our closest point comes at 10 a.m., where we’ll be about 3 percent closer to the Sun,” explained the exclusive site. EarthSky.
What is a subsaurus?
The word perihelion comes from the Greek roots “peri” meaning near and “helios” meaning sun.
The astronomical phenomenon that means that the farther a planet is from the Sun, the slower its displacement, a phenomenon known as apogee. On the other hand, the closer it is to the larger star, the faster it moves.
On social networks, some people have said that due to its proximity to the Sun during the subsolar we may have a climate with high temperatures, but it is not so.
“The seasonal behavior of climate is primarily influenced by the 23.44° inclination of our planet’s axis of rotation with the plane of its orbit, and not from its elliptical orbitexplained George Lebow, professor of astronomy at the University of Florida.
“During the Northern Hemisphere winter,[at this time of year]the North Pole is pointing away from the Sun. The days are shorter and this creates more cold. The fact that we are slightly closer to the Sun It does not matter, It’s freezing anyway,” he told an article published by NASA.
