NASA uncovers two low-density giant planets
NASA has announced the discovery of two low-density giant planets orbiting a star similar to the Sun, known as "TOI-791," located approximately 1,113 light-years from Earth. The planet "TOI-791 b" is similar in size to Jupiter but has only 3% of its mass, while "TOI-791 c" is larger than Jupiter and has 5.9% of its mass. Scientists were able to precisely study their characteristics using data collected over a seven-year mission. Their gravitational effects influence the timing of their transits across the star, contributing to our understanding of planetary formation and the evolution of planetary systems.
