The terms perihelion and aphelion describe the closest and farthest distances of the Earth to the Sun, respectively. The Earth is closest to the Sun (at perihelion) roughly 2 weeks after thewinter solsticeand farthest from the Sun (at aphelion) roughly two weeks after thesummer solstice. Yet ...
Mars' orbit is more elliptical (椭岗的) than Earth's, so the dilference between perihelion and aphelion(远日点) is greater. Over the past centuries, Mars' orhit has been getting more and more elongated, carrying the planet even nearer to the sun at peribetion and even larther away at...

Dates of passage of the Earth at its aphelion and perihelion are not regular. For the Sun we speak of a Aphelion (from the Greek "apo" away and "helios" sun), the farthest point between the object and the Sun and a perihelion ("peri" around and "helios" sun) , the nearest point....
Mars' orbit is more elliptical(椭圆的) than the Farth's, so the difference between perihelion and aphelion(远日点) is greater. Over the past centuries, Mars' orbit has been getting more and more elongated, carrving the planet even nearer to the Sun at peribelion and even farther away at...
This year, Earth perihelion happens on Jan. 4 at 11:17 a.m. EST. At that time, Earth will be approximately 91.4 million miles from the sun. (NASA) When the opposite occurs and Earth is at its farthest point in orbit from the sun, it's known as aphelion, which this year occurs on...
