- The most spherical natural object ever measured is the distant star Kepler 11145123, about 5,000 light-years away.
- By studying the star's oscillations, astronomers found its equatorial and polar radii differ by only about 3 kilometres, against a mean radius of about 1.5 million kilometres.
- It rotates once every 100 days, far more slowly than the Sun, which helps keep it so round.

By studying the star's oscillations, astronomers found its equatorial and polar radii differ by only about 3 kilometres, against a mean radius of about 1.5 million kilometres. It rotates once every 100 days, far more slowly than the Sun, which helps keep it so round. By comparison, the Sun's equatorial radius is only about 5 kilometres greater than its polar radius, while Earth departs from a perfect sphere by about 0.43 percent.
