A Super-Puffed Giant: WASP-193b’s Surprisingly Low Density and Well-Aligned Orbit

WASP-193b is an extremely low-density super-puff planet, with a size similar to Jupiter but a mass closer to Neptune. Unlike other super-puffs with tilted orbits, it follows a well-aligned path around its star. Researchers used the Magellan Clay Telescope to refine its properties and confirm its unusual density. Future studies, including those with JWST, may reveal whether WASP-193b is actively losing mass, shedding light on how such planets form and evolve.
