That, in turn, would mean less unlivable ice-covered regions and the potential for more habitable zones.
That was the focus of a recent study published in The Astronomical Journal. Modeling data from our solar system as we understand it today, University of California, Riverside (UCR) scientists created a theoretical system that slightly altered Jupiter's orbit.
"Many are convinced that Earth is the epitome of a habitable planet and that any change in Jupiter's orbit, being the massive planet it is, could only be bad for Earth," Pam Vervoort, a UCR Earth and planetary scientist and lead author of the study, said in a news release.
"We show that both assumptions are wrong." A slight change in Jupiter's orbit could also have the potential to turn portions of our planet into a subfreezing hellscape. If Jupiter positioned itself closer to the sun in its new orbit, it would create extreme tilting of Earth, causing some regions to see fewer solar rays.
Seeing how small changes to Jupiter's positioning and orbit lead to dramatic changes on Earth, the researchers are planning to develop methods to help them estimate factors beyond an orbit-like measuring a planet's mass and determining tilt-to figure out the volume of rays certain areas will receive.
"It's important to understand the impact that Jupiter has had on Earth's climate through time, how its effect on our orbit has changed us in the past, and how it might change us once again in the future," Stephen Kane, a UCR astrophysicist and study coauthor, says in the release.-Tim Newcomb

Whether We Live in a Simulation - scientist Melvin Vopson, PhD, studies this exact thing- the possibility that the universe might indeed be a digital facsimile. And he claims to have evidence.
In the 1999 film the Matrix, Neo discovers A truth to end all truths-the universe is a simulation. While this premise provides fantastic sci-fi fodder, the idea isn't quite as relegated to the fiction section as one might expect. . In fact, University of Portsmouth scientist Melvin Vopson, PhD, studies this exact thing- the possibility that the universe might indeed be a digital facsimile. And he claims to have evidence.
The Ancient Language of Easter Island - Today, humans inhabit- or have, at the very least, explored- pretty much every corner of the planet. But that immense proliferation of Homo sapiens across the globe was a slow process.
With the first humans leaving Africa between 60,000 and 120,000 years ago, the species slowly spread across the Earth over many millennia. And one of the last places these ancient humans made their way to was the southeastern Pacific island of Rapa Nui, known more broadly as Easter Island.Located 2,360 miles off the coast of Chile, Rapa Nui is one of the most isolated places in the world. Its native people, who are also named the Rapa Nui, first arrived on the island's shores between A.D. 1150 and 1280, and lived in isolation until the arrival of Dutch navigator Jacob Roggeveen in 1722.
Underwater UFOs - A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies.
A retired U.S. Navy admiral believes that the government should look to the oceans to help solve a mystery in the skies. Rear Admiral Timothy Gallaudet, former Oceanographer of the U.S. Navy, recently published a paper arguing that unidentified anomalous phenomena (UAP, more commonly referred to as UFO) and unidentified submersible objects (USO) are linked, and should be studied further.
Synching Up Our Circadian Rhythms - If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is.
If you've ever done any kind of long-distance travel, or just woken up feeling under-rested thanks to daylight saving time, you know how important your circadian clock is. Like many things in your body, your circadian rhythm is more complicated than it might seem on the surface. Rather than being entirely brain-based, it's actually controlled by a collection of several circadian clocks (central and peripheral) that all work together to keep your gears turning like a well-oiled machine.
