Don`t Panic, But the Sun Will (Far) Outlive Earth (Op-Ed)
... This 10% increase in the sun’s brightness, triggering the evaporation of our oceans, will occur over the next billion years or so. Predictions of exactly how rapidly this process will unfold depend on who you talk to. Most models suggest that as the oceans evaporate, more and more water will be pres ...

... The radius of the Earth is about 6380 km so the point that both the Earth and Moon are circling is located about 1/4 of radius of the Earth underground. This results in the Earth ‘wobbling’ with a roughly 30 day period as it orbits the Sun. You can apply the same process to other pairs of objects. ...
