This thursday 6 of July 2023 Earth experiences the phenomenon known as the aphelion And here we detail what this event consists of, as well as the consequences that it will bring to life on the blue planet. It will be on this date our home is at the point Further of the Sun and is the counterpart of the perihelion that occurs at the beginning of January each year and is when, on the contrary, the mass is at its closest point with the solar star.
He aphelion It occurs in the first days of July, the date on which Independence Day is celebrated in the United States and it is an event in which the Earth is the further away possible from sun, at an average distance of 152.1 million kilometers, or as a percentage, 1.67% further from the Sun than the average separation between the two masses. This phenomenon causes many doubts among people, because some do not explain how it is that being further away the planet also registers high temperatures.
Even though he aphelionthat this 2023 happens on thursday july 6, it is when the Earth is farthest from the Sun, the high temperatures continue to occur due to the axial inclination of the planet, in opposition to our distance from the sun, so the angle of inclination causes the solar rays to hit our home in a way more direct. The counterpart of this phenomenon; he perihelion It took place on January 4, 2023 and it was when it was closest to the solar star, at a distance of 147.1 million km.
Why does the EARTH experience APHELION?
May the Earth experience the aphelion and perihelion is due to the simple reason that the planet is not a perfect circle. The degree to which our home’s orbit diverges from a perfect circle is known as its eccentricity. Of all the planets in the solar system, Venus has the most circular orbit, so it oscillates between 107 million and 109 million km from the sun.
He aphelion in 2022 and 2021 it happened on July 4, and this year will take place 2 days later; that is, the July 6th at 2:06 p.m. from the center of Mexico when the Earth and the Sun take a difference of 4 million 994 thousand 326 km. During this event, the planet is also moving faster; at about 29.29 km/s, while at perihelion it does so at about 30.29 km/s.
To give you an idea of how fast the Earth moves during aphelion, it would take about 7 minutes to cross the entire Earth and it would take only 4 hours to reach the Moon. As of the occurrence of this phenomenon at 2:06 p.m. Central Mexico time, our home will shorten its distance from the Sun to get as close as possible to it on January 2, 2024 at perihelion of that year. The next aphelion It will happen on July 4 of the same year.
