34. Proper Distance From A Sun
When it comes to the sun, we need to be at the right distance. Too close and we’ll overheat but too far and we’ll freeze. Therefore, we must be in a habitable zone for it to even be possible for humans to stay on this planet for an extended period of time.
Ultimately, we need to be in what is known as the “Goldilocks Zone.” This is an area where it is neither too cold or too hot. This may differ distance-wise from planet to planet. For example, if the planet is larger, then the distance a habitable planet may change.
