I’m thinking about 1 mile away or closer to the sun.

Answer 1

For comparison,

> It is estimated that the Sun has become 30% brighter in the last 4.5 billion years.[125] At present, it is increasing in brightness by about 1% every 100 million years.[126]

A 1% change in luminosity would be equivalent to a change in distance of about 0.5%, or about 700,000 km.
Counterbalancing that, the greenhouse effect was *much* greater 100 million years ago.
