the earth is about 93 mil miles from the sun
and 5% closer is how much?
I think you missed Nosy's point. The Sun-Earth distance varies throughout the year, it is not a fixed distance. They vary
about 4% of the original 93 mil miles that you refered to - coming as close as 91 mil miles, and as far as 95 mil miles.
The variation that you said isn't possible is part of the normal variation in our elliptical orbit.
Also, what happens when the Sun enters the Red Giant stage (about 5 billion years)? - As a red giant, the Sun will extend beyond the Earth's current orbit, so what happens to our "perfect" position then?
And that's not even the beginning of life on Earth ending. Before it even gets to the Red Giant stage, every 1 billion years or so, the Sun's surface temperature will slowly rise by about 10%. The increase in temperature will make the surface of the Earth too hot for liquid water to exist, ending all terrestrial life.
Not such a perfect situation, eh?
