thats because the perspective is screwed up!. The planet is not actually behind them but under them. If you see some mockups about the wrong perspective issues on the death star you will see that endor can be visible. Also if you see TFU cutscenes you will notice too that the exterior superstructure is visible too! They used that pic of deathstar like a stencil instead of using other angles of that beautyfully done Prop!
