The gas giant's shape and size, previously known only from data collected more than 45 years ago, have been updated. New measurements indicate the Solar System's largest planet is smaller in radius and exhibits increased oblateness compared with earlier values. The revised dimensions replace decades-old estimates and provide a more accurate physical description of the planet. Updated size and shape parameters will refine measurements that depend on planetary dimensions. The changes are based on more recent observational data and offer a corrected baseline for future comparative and theoretical studies of giant-planet structure and rotation.
