Orbital shape is basically how \u201cstretched\u201d Earth\u2019s path around the Sun becomes, and that stretch affects seasonal contrasts and long-term ice growth.<\/p>\n\n\n\n<div class=\"gb-element-f87a7b99\">\n<div><div class=\"gb-looper-280b0d2d\">\n<div class=\"gb-loop-item gb-loop-item-d4438a1b post-29117 post type-post status-publish format-standard has-post-thumbnail hentry category-science resize-featured-image\">\n<h3 class=\"gb-text gb-text-5426299a\">Read More: <a href=\"https:\/\/www.ecoticias.com\/en\/the-giants-of-the-past-did-not-run-as-we-thought-and-science-has-just-taken-an-unexpected-turn-in-the-classic-image-of-mammoths-and-dinosaurs\/29117\/\">The giants of the past did not run as we thought, and science has just taken an unexpected turn in the classic image of mammoths and dinosaurs<\/a><\/h3>\n<\/div>\n<\/div><\/div>\n<\/div>\n\n\n\n<p>In the results, a long cycle tied mostly to Venus and Jupiter stayed in place even when Mars was taken out. But two other prominent cycles, one around 100,000 years and another around 2.3 million years, disappeared entirely without Mars in the model.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why orbit changes can reshape climate<\/h2>\n\n\n\n<p>These orbital cycles do not flip the weather forecast next week. Instead, they nudge how much summer sunlight reaches high latitudes, which can decide whether winter snow melts away or piles up into ice sheets over time.<\/p>\n\n\n\n<p>That slow build matters because ice sheets change sea level, winds, and ocean circulation, and they can rewrite coastlines that people would later live on. In other words, the \u201cbeat\u201d of ice ages can ripple into the planet you inherit, even if it takes thousands of generations to notice.<\/p>\n\n\n\n<figure class=\"wp-block-image size-full\"><img loading=\"lazy\" decoding=\"async\" width=\"1800\" height=\"1013\" src=\"https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/03\/mars-earth-orbits-ice-age-climate-cycles.jpg\" alt=\"Diagram comparing the orbits of Mars and Earth around the Sun, illustrating research on how Mars may influence Earth\u2019s long climate cycles.\" class=\"wp-image-29202\" title=\"\" srcset=\"https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/03\/mars-earth-orbits-ice-age-climate-cycles.jpg 1800w, https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/03\/mars-earth-orbits-ice-age-climate-cycles-300x169.jpg 300w, https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/03\/mars-earth-orbits-ice-age-climate-cycles-768x432.jpg 768w, https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/03\/mars-earth-orbits-ice-age-climate-cycles-1536x864.jpg 1536w, https:\/\/www.ecoticias.com\/en\/wp-content\/uploads\/2026\/03\/mars-earth-orbits-ice-age-climate-cycles-150x84.jpg 150w\" sizes=\"auto, (max-width: 1800px) 100vw, 1800px\" \/><figcaption class=\"wp-element-caption\">A simple orbit diagram shows Mars and Earth circling the Sun, reflecting the gravitational link that researchers say may help shape Earth\u2019s ice age rhythms.<\/figcaption><\/figure>\n\n\n\n<h2 class=\"wp-block-heading\">A clue for worlds beyond our solar system<\/h2>\n\n\n\n<p>The researchers also tested what happens if Mars were heavier.
