One mile is a tiny distance compared to the vastness of space and the distance between the Earth and the Sun. So, moving the Sun one mile closer would have no noticeable effect on Earth.

Here's why:

* The Sun is incredibly far away: The average distance between the Earth and the Sun is about 93 million miles. One mile is a minuscule fraction of that distance.

* The Sun's energy output is relatively stable: The Sun's energy output varies slightly over time, but these variations are too small to be noticeable with a one-mile shift in distance.

* The Earth's orbit is not a perfect circle: The Earth's orbit is slightly elliptical, meaning it's closer to the Sun at certain points in its journey than others. A one-mile change wouldn't even be noticeable within the natural variations of our orbit.

In short, moving the Sun one mile closer would have no significant impact on Earth.
