Researchers discover "super fluffy" planet with cotton candy-like density

On Monday, astronomers announced the discovery of a massive planet 1,200 light-years away from Earth that has a density similar to cotton candy.   

Based on research published in Tuesday's issue of Nature Astronomy, WASP-193b is an exoplanet,  

meaning it is situated outside of our solar system. Jupiter, the largest planet in our solar system,   

is half as big as this object, but its extremely low density makes it seven times less massive.   

Planet Earth is so very light that it's hard to imagine a solid-state substance that is similar,   

according to MIT professor and study co-author Julien de Wit, who stated in a university news release.  

Since both are essentially air, that's why it's so similar to cotton candy. To put it simply, Earth is quite fluffy.  

Scientists have found almost 5,000 exoplanets so far, but WASP-193b stands out due to its very low density.
