The Effect of the Solar Sale on the Earth's Orbit

The sun is pulling on swith gravity, and that's an attractive force. And it's also very gently pushing on us.

So we are getting pushed by the sun, but it's a really tiny amount compared to all the other forces in the mass of the earth. But you know, you can never really discount stuff in astronomy."
