Every planet that you see is sort of ball shaped, as planets are formed by destroyed stars etc, you would think there would be a few odd shapes out there?????????
And where did you observe all stars to be round ! From the naked eyes everything in the sky is a dot !
Its's all to do with the gravitational pull of the stars they rotate around and their sheer size and mass. Things like asteroids tend not to be round because they are usually only fragments..
hehe, would that made earth round ? btw do u know earth is ovel shaped ... wonder which start broke in such artistry
Th3ese are not all same size or same radius, But.. you would think that after a star collapses etc, there would some odd shapes orbiting, but I guess as gravitation pulls and the rotation a ball shape is the most obvious shape...
will there be some humans with tails? well actually you have asked an interesting question, i love to answer such questions the answer here is only a spherically shaped body revolving around a star is entitled to be known as a Planet, there are plenty of other shapes as well but we humans call all others as asteroids.................
