This planet is 150 percent the size of Jupiter, but is somehow 7 times less dense, and has 1 percent the density of Earth.

Astronomers have identified a planet that’s bigger than Jupiter yet surprisingly as fluffy and light as cotton candy. The exoplanet has exceedingly low density for its size, an international team reported Tuesday.

WASP-193b is 50% larger than Jupiter — the largest planet in our solar system — but seven times less massive because of it's extraordinarily low density.

An international team led by researchers from the EXOTIC Laboratory of the University of Liège, in collaboration with MIT and the Astrophysics Institute in Andalusia, has just discovered WASP-193b, an extraordinarily low-density giant planet orbiting a distant sun-like star.

A new, giant exoplanet — the second least dense known so far — has been discovered about 1,200 light-years away from Earth. Astronomers behind this discovery describe the density of this new planet as almost “similar to that of cotton candy.
