Mars' gravity has a surprisingly large influence on Earth, affecting our planet's tilt and orbit and thereby contributing to climate cycles lasting hundreds of thousands to millions of years, new ...

Earth's climate has swung between ice ages and warmer periods for millions of years, driven by subtle changes in our planet's orbit and axial tilt. These variations, known as Milankovitch cycles, ...

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 ...

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

Compared with Earth, Mars is tiny, yet it seems to have an outsized effect on our planet’s climate cycles. Similar small planets could affect the climates of worlds beyond our solar system, which we ...
