That's an interesting point.
You'd also want to factor in when you fly in an airplane, you cruise at X,000 feet, and how much bigger is the sun? And extrapolate from there.
I can extrapolate.
I fly frequently in the years since I became a flat earther. I always ride in a windowseat now for this reason.
On midday flights, you can take great photos of the sun at zenith (midpoint, or "high noon") when you fly under it. The sun appears bigger at zenith from your aircraft vantage point than it does at zenith from on the ground.
Think about that for a minute.
If average cruising altitude is 36,000 feet (6.8 miles) why does the sun look bigger, if you are only a little over six miles closer?
Because it's not that far away!
If the sun was 93 MILLION miles away, being 6.8 miles closer is NOT going to change its appearance.
But, it does, so that means it is much, much closer than 93M miles.
