Jupiter and Venus Change Earth’s Orbit Every 405,000 Years

Over the course of the past 200 million years, our planet has experienced four major geological periods (the Triassic, Jurassic and Cretaceous and Cenozoic) and one major ice age (the Pliocene-Quaternary glaciation), all of which had a drastic impact on plant and animal life, as well as effecting the course of species evolution.

For decades, geologists have also understood that these changes are due in part to gradual shifts in the Earth’s orbit, which are caused by Venus and Jupiter, and repeat regularly every 405,000 years. But it was not until recently that a team of geologists and Earth scientists unearthed the first evidence of these changes – sediments and rock core samples that provide a geological record of how and when these changes took place.

...

Earth experiences periodic changes in its climate (which are related to changes in its orbit) has been understood for almost a century. These changes consist of Milankovitch Cycles, which consist of a 100,000-year cycle in the eccentricity of Earth’s orbit, a 41,000-year cycle in the tilt of Earth’s axis relative to its orbital plane, and a 21,000-year cycle caused by changes in the planet’s axis.

Combined with the 405,000-year swing, which is the result of Venus and Jupiter’s gravitational influence, these shifts cause changes in how much solar energy reaches parts of our planet, which in turn influences Earth’s climate.

...The heart-ache and the thousand natural shocks
That flesh is heir to, ‘tis a consummation
Devoutly to be wish’d. To die, to sleep;
To sleep: perchance to dream: ay, there’s the rub;
For in that sleep of death what dreams may come
When we have shuffled off this mortal coil,
Must give us pause...

Now, since the sea’s great surges sweep me on, all canvas spread, hear me!
In all creation nothing endures, all is an endless flux.
Each wandering shape a pilgrim passing by, and time itself, glides on in ceaseless flow.
A rolling stream, and streams can never stay, nor lightfoot hours,
as wave is driven by wave, and each pursued, pursues the wave ahead.
So time flies on and follows. Flies and follows always, forever new.
What was before is left behind. What never was is now...

[Ovid, “The Doctrines of Pythagoras,” The Metamorphosis]
