“A mystery surrounds the shape of the Sun – it is just too perfectly round, scientists have said. In fact the Sun turns out to be one of the roundest objects ever measured. Scaled down to the size of a beach ball, the difference between the Sun’s widest and narrowest diameters would be far less than the width of a human hair. Having no solid surface, the Sun’s rotation should make it slightly flattened. But the new measurements show that the flattening is much smaller than expected.” w/ photo
