Thread: A Sphere - and Corners?

Hello I'm currently on the verge of asking if a sphere (in the sense of an actual object, as in planet, star, basketball whatever) can actually have four corners, one for each major point of the object in question.

I'm assuming this is done by applying a virtual "mesh" around the sphere, in which case, you could have a bunch of dots on top of it! Even then, does this idea have credentials or is it just my imagination at play?

What I'm really asking is could there be some mathematical or otherwise easy way to find out if a sphere could have this property.

From my current knowledge, my best guess is that spheres have a circular shape, and don't end at any specific point. But if there is at least a way in math to figure this out I'd like to know that may contradict my theory...

I'm not really sure what you are asking, but I think the most efficient way of laying out a coordinate system on a sphere is with lines of latitude and longitude.

Maybe. I'll have to rephrase my question and post again soon if I think of what I meant right.
