What happens if earth moves away from the sun

Without land to absorb some of the sun's heat, temperatures on Earth would continue to rise. Temperatures also would see a boost from rising levels of the carbon dioxide and vapors that the oceans released into the air [source: Nevins ]. Conversely, a shift in the orbit moving Earth farther from the sun would cool and potentially freeze the planet. Oceans would be covered in ice, causing them to release less carbon dioxide and vapor.

It would also make years longer; the farther the planet is from the sun, the longer it takes to complete its annual orbit [source: Nevins ]. That's not to mention the effect that a shift in Earth's orbit would have on the rest of the solar system. Even a minor change in its path around the sun could cause planets to collide.

It also could throw off Earth's delicate positioning with Jupiter. The largest of the eight planets acts as a shield of sorts, deflecting harmful gases and asteroids that might otherwise be bound for Earth [source: Howell ]. Sign up for our Newsletter!

That's as hot as an average summer day in Death Valley, one of the hottest places on Earth.

Most mammals, birds, and insects die as the proteins that make up their cells start to cook. Yes, even roaches can't withstand this apocalypse. If we want to live, we need some indoor air-conditioning, stat. Except, the amount of energy you need to run millions of AC units at once would wipe out power grids around the world. So, with no way to keep cool, humanity dies. By day 41, the Earth has passed by Venus. We're now the second planet from the sun, and temperatures have climbed to 66 degrees.

But believe it or not, some creatures still cling to life. Like Thermus aquaticus , a bacteria that lives in Yellowstone's hot geysers. Intermediate Is the Moon moving away from the Earth?

Editor's Pick. What is the universe expanding into? Intermediate What do I need to do to become an astronomer? The sun and Earth are moving apart by about 15 cm per year — the culprit may be tides raised on the sun by our home planet. Skywatchers have been trying to gauge the sun-Earth distance for thousands of years. In the third century BC, Aristarchus of Samos, notable as the first to argue for a heliocentric solar system, estimated the sun to be 20 times farther away than the moon.

By the late 20 th century, astronomers had a much better grip on this fundamental cosmic metric — what came to be called the astronomical unit.
