This question is a bit complicated, or at least from my end, but I've spent quite a while trying to solve it on my own without luck. I feel like I should have the information I need, but I can't figure out how to reference the variables together to make them work.
This is the basic premise, take the image I've got here.
Since it doesn't really have depth, I'll explain it. Basically, we have a person falling through a tunnel, so the person is flat parallel to the top of the ground, let's say and falling directly down. The tunnel (which is a cylinder) is the brown section, the outer circle being the entrance and inner circle being the exit of said tunnel. The person is currently above the entrance of the tunnel. Finally, the earth-like circle in the back is a very large sphere a long distance away.
Here, I've crudely drawn what this should look like from above the perspective given in the original image. Now, I have the angular diameter of every single circle shown, and I also have the real diameters as well as distance to the person falling and the far away sphere. We also know that the tunnel is a cylinder, and therefore the real diameter of the two inner circles are equal. However, we don't know their real diameters or their distance away from us or each other. Can we find their real diameters or distance away with the information we currently have? If so, how? Thanks!
