Scientists claim Earth could be more habitable by shifting Jupiter’s orbit : Okezone techno

JAKARTAEarth increasingly uninhabitable due to exploitation by humans. However, recent studies have revealed that this critically endangered planet can actually be cured.

The way to do this is by shifting Jupiter’s orbit a little, as said by planetary scientist Pam Vervoort of the University of California, Riverside.

“If Jupiter’s position remained the same, but the shape of its orbit changed, it could actually increase the habitability of the planet,” said Vevoort, quoted from ScienceAlert, Friday (23/9/2022).

“Many believe that Earth is the epitome of a habitable planet and that any change in the orbit of Jupiter, as a massive planet, can only have a negative impact on Earth. We show that both assumptions are wrong,” he added.

Currently, Jupiter has an almost circular orbit. However, if the orbits were stretched, it would have a tremendous effect on the rest of the Solar System because Jupiter is very large, 2.5 times the mass of all the planets in the Solar System combined.

For Earth, the shift in orbit means an increase in eccentricity. This means, the researchers found, that some parts of the planet will be closer to the Sun, warming up to a temperate and habitable range.

However, if Jupiter moved closer to the Sun, Earth’s habitability would decrease. That’s because it caused the Earth to tilt more sharply on its axis of rotation than it currently does, giving us more seasonal variation.

A sharper slope would cause much of our planet to freeze, with more extreme seasons. Winter sea ice will expand into other areas, four times as large as it is today.

The researchers say these results can be applied to any multi-planet system that has been discovered, to assess their habitability potential.

This latest study breaks an earlier study, conducted in 2019, in which an international team of researchers said changing Jupiter’s orbit could very quickly destabilize the entire Solar System.

“It’s important to understand the impact Jupiter has on Earth’s climate over time, how its influence on our orbit has changed us in the past, and how it may change us once again in the future,” said astrophysicist Stephen Kane of the University of California, Riverside.
