orbit

Who knew? The orbits of planets hundreds of millions of miles away can change weather patterns here on Earth.

Every 405,000 years, gravitational tugs from the planets Jupiter and Venus gradually affect Earth’s climate and life forms, according to a new study published Monday.

In fact, this pattern has been going on for at least 215 million years and allows scientists to more precisely date geological events like the spread of dinosaurs.

“Scientists can now link changes in the climate, environment, dinosaurs, mammals, and fossils around the world to this 405,000-year cycle in a very precise way,” said study lead author Dennis Kent, an expert in paleomagnetism at Columbia University’s Lamont-Doherty Earth Observatory and Rutgers University.

The cycle has been happening for hundreds of millions of years, from before the rise of dinosaurs, and is still active today, scientists say.

“The climate cycles are directly related to how the Earth orbits…
