Less about size and more about size and relative distance. Think about being on Mercury and the entire sky is blazing sun - and yet it survives.

I've never thought about this and holy shit

That's not the case though. Sure the sun would seem bigger on mercury but it's not gonna fill the entire sky.

Edit: According to NASA the sun would appear 3 times bigger and 7 times brighter on mercury.

I mean, nothing on Mercury survives. At night it's -170 degrees Celsius and +430 degrees at day.

There was a time people thought Mercury would have some "twilight" acreage that was always at habitable temperatures. Then we learned that, while yes it is tidally locked with the Sun, it is locked in a 3:2 resonance so it does rotate with respect to the sun, and everywhere gets both scorched and frozen to uninhabitability.

So we just need movable habitats like in Howl’s Moving Castle or Mortal Engines
