Hmm, do we even need trig? Naively I would imagine that simple proportions would hold — e.g. same visible size @ twice the distance = object is twice as big

- californical 4y ago4x as big, since we see in two dimensions — you can judge length & height (but not depth). So if it appears the same size but twice as far away, the the length and height are each 2x. So that would make it the size of ~4 airplanes
- Miserlou57 4y agoNot super relevant but I find this to be true when spotting a 747/757/767 vs say a 737
- d0mine 4y agothe area is 4x but the diameter is just 2x here.
- ant6n 4y agoIsn’t the object three-dimensional?
