"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if ...

New simulations show red planet affects Milankovitch cycles that shape how solar energy is distributed on Earth over millions ...

At half the size of Earth and one-tenth its mass, Mars is a featherweight as far as planets go. Yet new research reveals the extent to which Mars is quietly tugging on Earth's orbit and shaping the ...

Milankovitch cycles describe slow, predictable changes in Earth’s orbit and tilt that influence long-term climate patterns.

Changes in Earth's orbit have helped pace climatic change for millennia. Scientists are now trying to understand whether - and how - these changes remodeled the landscapes our ancient ancestors ...

New simulations show Mars plays a key role in shaping Earth’s long-term climate by influencing its orbit and axial tilt over hundreds of thousands to millions of years.

This doesn’t mean Mars causes ice ages on its own. Orbital cycles are only part of the picture. Earth’s oceans, atmosphere, ...

Research suggests that Mars may strongly influence these cycles. For example, Mars helps drive a 2.4‑million‑year cycle linked to Earth’s gradual shift in its closest point ...

Previous research on deep-sea sediments had suggested that Mars might influence Earth's climate, but the magnitude of this ...
