Theta = 1/2 human fov

r = radius of sun

so simple (and not at all). Thanks.

If you're so good at maths, can you tell me how a cord devide the radius? Or something to that extent. I know the chord's lenght, and the minor segment's height. Now to modell this I probly need a cylinder and cut the major segment off, but to get the right size I need the r. Don't I? Am I going insane?

edit: lmao google IS my friend 1000013490

d = r/sinΘ

Human FoV is about 210° with both eyes. Thus Θ is 105°.

The radius of the sun is 695,508 km.

Thus, d is 695,508/sin(105) → 720,043 km

720,043 - 695,508 = 24535 km away from the surface of the sun.

However, because the FoV is greater than 180°, this is actually below the surface of the sun, and any distance below the surface is enough to fill your vision.

To completely fill your field of view with the Sun, you'll need to take a Parker Bath and dip into the sun.

I think 210° is when you moved your eyes to the limit at both sides. So let's say it's FOV when your eyes look straight forward and don't move.

The 210 is straight ahead horizontal FOV, i just didn't realize it was greater than 180°, which means it can technicaly never completely fill your peripheral vision. Your binocular vision with both eyes is around 115°. Vertical fov is only 135° though.
