SPACE.COM - University of California-Riverside (UCR) scientists simulated alternative arrangements of our solar system, finding that when Jupiter's orbit was more flattened — or 'eccentric' — it would cause major changes in our planet's orbit too.
And this change caused by the orbit of Jupiter — the solar system's most massive planet by far — could impact Earth's ability to support life for the better.
"If Jupiter's position remained the same, but the shape of its orbit changed, it could actually increase this planet's habitability," study leader and UCR Earth and planetary scientist, Pam Vervoort, said. "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.
"We show that both assumptions are wrong."
