There must be. When you’re standing on the moon, it goes on as far as the eye can see, and the Earth is a ball in the sky. The moon is 27% of the diameter of the earth, so o you need to be at a spot where the Earth is 3.7 (=1/0.27) times further away from you than the moon. That’s 50,789 miles above the moon’s surface, 188,110 miles above Earth.
