On Friday, 10:46, this week, Earth will witness a rare event that occurs only one time a year. It’s called Aphelion. The opposite sibling is Perihelion.
The one that observed the two phenomena was Johannes Kepler that lived in the sixteenth century. He found out that orbiting objects are having a higher speed at perihelion and slower at aphelion. Mark Hammergren, an astronomer at the Adler Planetarium in Chicago said that the mathematician “figured out the orbits of the planets were elliptical in shape and that the Sun was offset from the center.”
All depends on the angle
George Lebo, a cosmologist at NASA’s Marshall Space Flight Center in Huntsville, stated that seasons are “shaped primarily by the 23.5-degree tilt of the planet’s spin-axis and not by the mild eccentricity of Earth’s orbit.” The tilt of the planet influences whether the Sun’s energy will strike the Earth at a low angle or more directly. Heat received by any region is depending on the position of the Sun higher up at the horizon.
Generally, the Aphelion happens two weeks after the June solstice, during the first day of winter in the Southern Hemisphere and the first day of summer in the Northern Hemisphere. Earth’s is not a perfectly round planet. And every celestial body has a specific spot where it is neighboring the Sun very near and another where it is at a maximum distance from it. But humans don’t have the potential to recognize the changing of speed or distance with the bare eyes.
Distance won’t disrupt the July heat
July is a summer month, and the warm weather is baking in heat waves the population. Surprisingly, at that time the Earth is situating in space the farthest from its star. While January comes with snow, cold winds, ice all over the place, Sun neighbors the Earth closer. Perihelion comes with a higher intensity of light, in comparison with the sunlight that comes on Earth in July.
Sun rays are less intense in the Northern Hemisphere, during July than in the Southern. At the first sight, this is not possible. The right explanation comes with the fact that our planet contains oceans. The water stores the heat and keeps a balance for seasons.
Shawn and his wife live remotely in a 880-square-foot cabin along with their three dogs. They implemented many of the things they learned from the internet and trial and error. They have been helped by so many contributors over the years and desire to now return the favor to other Canadian Homsteading readers. They heat with a woodstove and cut firewood by hand from their 11 acres. They went back to the land and are essentially do-it-yourself people.
