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 ...

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 ...

A new study suggests Mars's gravitational pull significantly impacts Earth's orbit, driving the intensity of ice ages and warm periods. Learn how planetary cycles control our planet's long-term ...

As an astronomer studying the universe beyond Earth, I’m fond of “outside the box” views almost by default. But one of my favorites is whenever a spacecraft takes a snapshot of our home world and the ...

"Without Mars, Earth's orbit would be missing major climate cycles. What would humans and other animals even look like if Mars weren't there?" When you purchase through links on our site, we may earn ...
