Jupiter and Venus distort the orbit of the Earth

Gravity of Jupiter and Venus can affect Earth's orbit around the Sun in a cycle of hundreds of thousands of years.

Scientists have confirmed a long-held hypothesis that the Earth's orbit is deformed by Jupiter's gravitational force and the 405,000-year cycle , which affects climate and forms. life on Earth. The results of the study are published in the Proceedings of the National Academy of Sciences (PNAS) on May 7.

In fact, this cycle has been going on for at least 215 million years. It happened before the dinosaurs developed and still works today. Based on the cycle, we can more accurately determine the date of geological events.

"Scientists can now link changes in climate, environment, dinosaurs, mammals and fossils around the world with a 405,000-year cycle clearly" , Dennis Kent, The main author of the study at Rutgers University (USA), said.

According to Kent, climate cycles are directly related to how the Earth orbits the Sun. Small changes in the amount of sunlight shining on Earth lead to climate changes and ecosystems.

Jupiter and Venus can cause such intense effects due to their close size and distance. Venus is the closest planet to Earth and has nearly the same mass as our planet. The time when Venus is the most distant from the Earth is only about 260 million kilometers. Jupiter is farther away from Earth but is the largest planet in the solar system.

According to the team, every 405,000 years, Earth's orbital shaking is caused by the gravitational pull of the two planets, which changes the state of the seasons on Earth. The summers get hotter and the winters get colder, the drought is less rainy and the wet season rains.

We are currently in the middle of the cycle, because the most recent cycle peak was about 200,000 years ago, Kent said.

However, the impact on the climate from the planets is too small compared to the way humans affect the Earth through burning fossil fuels.

"All of the carbon dioxide that people emit into the atmosphere today has a significant impact on the rise in global temperature. It's an effect that we can measure right now. The planetary cycle is something more subtle and difficult to detect , ' Kent said.
