The very first exoplanets were finally discovered in the early 1990s, and since then over 4,000 have been caught floating about in the inky pool of deep space. It’s clear that the cosmos is swimming with alien worlds, and some are pretty damn peculiar.

In recent years, astronomers have confirmed the existence of so-called “cotton candy” planets: portly, Jupiter-size worlds that are remarkably lightweight. These oddities have densities comparable to cotton candy, hence the moniker. Saturn is famous in our own solar system for being of such low density that it could float in a big enough bathtub, and these exoplanets make our stellar neighborhood’s gas giant look like a lead weight in comparison.
