You can see exactly half of the sphere at infinite distance and the closer you are the more of it is beyond your visual horizon, the confusion arises on people with low spatial intelligence from the fact that sphere will look round on all distances (because it is) while on every day scale with 2 eyes you can see pretty much "50%" of most spheres no matter the distance so your mind tricks you into thinking the visible portion must be half or at least nearly half of the entire object.
