WASP-193b is a hot, transiting gas giant planet located approximately 1,232 light-years (378 pc) away[4] in the constellation of Hydra, orbiting the F-type star WASP-193. Its discovery was made by the WASP-South transit survey and announced in 2023. The planet is extremely bloated, with a radius nearly 50% larger than Jupiter, despite having only 14% of its mass. This places its density at 0.059 g/cm3, the second lowest of any known exoplanet as of May 2024 after Kepler-51d, and comparable to that of cotton candy (about 0.05 g/cm3).
