WASP-17 is an exoplanet located approximately 1,000 light-years away in the constellation Hydra. It was discovered in 2009 and is classified as a hot Jupiter, meaning it is a gas giant that orbits very close to its host star, resulting in high surface temperatures. One of the most interesting features of WASP-17 is its low density, which suggests it has a large atmosphere and is less massive than similar-sized planets. This unique characteristic makes it an important subject for studying planetary formation and the dynamics of gas giants in close orbits around their stars.
