The Physics of Orbits

Anything that wasn't in an orbit basically fell into the sun or got thrown out and so anything that remains after all that time it should be in an orbit. If you don't have exactly the right value then physics will push you back towards having the right velocity and radius turns out that just from a gravitational point of view using Newtonian physics these orbits are stable. But there's lots of other things going on the sun is losing its mass the earth feels a solar wind etc etc There are other planets hugging on us so it's a little bit more complicated but in the simplified view of just a single planet orbiting a star then yes those orbits are stable oh I see wait wait until we get to
