Scientists spot 'roundest' object ever observed in nature

Germany-based researchers have discovered a star 5,000 light-years from Earth, described as the 'roundest' object ever observed in nature. Being twice as big as Sun with a mean diameter of 3 million km, the star's equatorial diameter is only 6 km more than its polar diameter. Notably, all celestial objects are 'slightly flattened' due to the centrifugal force of rotation.
