Every 2.4 million years, Mars tugs on Earth so hard it changes the ocean floor

Mars’ gravitational pull on Earth may be influencing the climate on our planet, new research hints.

Geological evidence tracing back more than 65 million years and taken from hundreds of sites across the world suggests that deep-sea currents have repeatedly gone through periods of being either stronger or weaker. This happens every 2.4 million years and is known as an “astronomical grand cycle.”
