A star some 5,000 light years from Earth has been hailed the roundest object in nature by a team of astrophysicists.The sun was previously believed to be the most perfectly round natural object in the universe.

Researchers at the Max Planck Institute, Germany measured the roundness of the star 'Kepler 11145123'. The team found that the difference between star's equatorial length and its polar axis is smaller than that of the sun, meaning it is more round in shape.

Laurent Gizon, the study's lead researcher, confirmed that Kepler 11145123 is now “the most rounded object ever observed in nature, rounder than the sun.” The team said the measurement was made with an accuracy of 1km.
