I am making a three.js sphere geometry with a radius of 4000, put a jpg on it and position the camera within it's center and it works fine.
When I make the sphere with a radius of 9000 so the texture shall look farer away it appears as if there was a black "hole" in the sphere in the very direction the camera is looking. Also the texture on the sphere looks nearer and not farer away. When I move the camera towards this "hole" it becomes smaller.
new THREE.SphereGeometry ( 9000 , 32 , 32 );
