Two giant planets are among the lightest ever found
Two giant planets, TOI-791 b and TOI-791 c, discovered around a star 1,110 light-years away, have densities lower than cotton candy, making them among the least dense planets ever found. Their rarity as 'super-puff' planets in the same system offers insights into planetary formation and evolution.
