The southern winter is longer because Mars is farthest away from the Sun then, moving more slowly in its elliptical orbit around the Sun.įor Mars, going from a colder winter to a warmer spring can be quite dramatic. The southern hemisphere of Mars has a warmer, shorter spring and summer than in the north, as Mars is closest to the Sun towards the end of southern spring. Mars also has four seasons but they are twice as long because it takes about two Earth years for Mars to go around the Sun. In comparison, Earth’s orbit seems almost circular this almost-circular orbit may be why Earth’s climate is relatively stable. Every planet has points in the orbits when they are farthest or closest away from their star.įor example, planet Mars has an even more elliptical orbit than Earth. Earth’s orbit around the sun isn’t a perfect circle. Though aphelion and perihelion are terms mostly used in reference to Earth since it’s our home planet, they are also relevant to other planets orbiting the Sun. The precise distance of an astronomical unit is 92,955,807 miles (149,597,871 km). Read more about the reason for the seasons! Aphelion and Perihelion on Mars It’s because Earth orbits the Sun on a tilt that our planet gets more or less of the Sun’s direct rays at different times of the year. According to wikipedia and other sources, a planet and a star always move in a circular orbit around the common center of mass of the both bodies, in case of Earth and sun, this center of mass lies inside the sun. It’s the not the distance from the Sun that causes our seasons. Seasons happen because Earth’s axis is tilted at an angle. This means that the Earth is rushing through space around the sun at a rate of about.

Are Aphelion and Perihelion Related to Earth’s Seasons? It takes 365 days, one year, for the Earth to go around the Sun once. About two weeks after the December Solstice, Earth is closest to the Sun.ĭid you know that the Moon’s orbit around the Earth is also elliptical? The point in the Moon’s orbit that is closest to the Earth is called the “perigee” and the point farthest from the Earth is known as the “apogee.” Perigee and Apogee are often confused. Perihelion always happens in early January.Aphelion always happens in early July. About two weeks after the June solstice, Earth is farthest from the Sun.Image credit: NASA (Note that “perihelon” should be spelled “perihelion” in this graphic. This year, Earth will be 91,403,034 miles away from the Sun at perihelion and 94,506,364 miles away from the Sun at aphelion. Eastern Time and will be at aphelion on July 6 at 4:06 P.M. In 2023, Earth is at perihelion on January 4 at 11:17 A.M. The words come from Ancient Greek, in which helios means “Sun,” apo means “far,” and peri means “close.” Perihelion and Aphelion in 2023 Perihelion is the point of the Earth’s orbit that is nearest to the Sun.Aphelion is the point of the Earth’s orbit that is farthest away from the Sun.(Like all stars, the Sun will eventually run out of energy – but scientists don’t expect this to happen for another 5 billion years or so. Instead, people build giant rocket thrusters to move the Earth to a new star system. In the 2019 film “The Wandering Earth,” once again the Sun is dying, but there’s no bomb this time. To save humanity, astronauts try to reignite the Sun with a bomb, though things don't quite go as planned. In the 2007 film “Sunshine,” the Sun is dying, plummeting Earth into a deep freeze.

Astronauts are supposed to use a bomb to divert the flare. In the 1990 science fiction film “Solar Crisis,” a huge solar flare is about to scorch Earth. If you're Superman or a fellow Kryptonian, your powers are heightened by the yellow glow of our Sun, and you can even dispose of dangerous materials, as Superman and Superboy did, by hurling them into the Sun. The Beatles had a hit in 1969 with “Here Comes the Sun.” Other popular songs that reference the Sun include: “Walkin’ on the Sun” by Smashmouth “Ain’t No Sunshine” by Bill Withers “Walking on Sunshine” by Katrina and the Waves “Pocketful of Sunshine” by Natasha Bedingfield and “Let the Sunshine In” by the Fifth Dimension.

Countless musicians have written songs about the Sun.
