How Stable Is the Earth's Orbit?

On this week's podcast we'll be asking the question. How stable is the earth's orbit? Never thought about the stability of our planet's orbit I guess. It seems so predictable and regular right? Nobody questions whether the sun will rise in the morning every day. But when you look on longer time scales hundreds of millions of years or billions of years you see the solar system is actually quite chaotic. Planets have been lost. They've changed their orbit. All sorts of crazy stuff has happened. So then you can ask like, well how long will this phase of our solar system last? Yeah I guess the solar system was just a giant cloud of dust and gas at some point right
