what about other planets and moons?

Are all planets flat? If so, what evidence is there of that? What about the moon? Is it flat or a sphere? If the moon and earth are flat, then there is one flat disk orbiting another? Is the moon a sphere orbiting a flat disk? Is earth flat but all other planets are spheres? Are all other moons of other planets disks or spheres? Are some a sphere, others disks? Are they all disks or are they all spheres? What about the sun? Is it a sphere or a disk? I eagerly await your answers!

Yes, all the "planets" are flat. Because of the pull of the Sun, we only see the faces of the planets so they may seem round. All the planets are oriented face-towards the Sun, when they go around the backside of the Earth, they are outside our sphere of vision.

Great question!
