- Researchers find 2 giant planets with density lighter than cotton candy
Researchers led by the University of Oxford discovered two 'super-puff' planets, TOI-791 b and c, with densities lighter than cotton candy. The planets orbit a dwarf star in the constellation Volan and are the lightest known planets of their size, according to the study published in Monthly Notices of the Royal Astronomical Society.
- 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.
