Our global environment is in a delicate balance. Concerns over global warming are directed at a few degrees Celsius of temperature change. Let's say that a 20ºC change would be catastrophic. Since solar flux is a function of R^2, that means that a 3,000,000 mile decrease in orbital radius will result in a net 20ºC increase in global temperatures.
A decrease of 10,000,000 miles in orbital radius will result in average global temperature exceeding the boiling point of water.

Assuming moderate velocity and taking certeris paribus into account.
I'm guessing not a whole helluva a lot closer than we are now. it would only take a fraction of a course change toward the sun to annihilate life on this planet.
p.s. I have no earthly idea what certeris paribus is....but it sounds interesting LOL!

Too close, even for an economist.
