If you could somehow place WASP-193b in a cosmic bathtub, it would float.. and not just barely. This exoplanet, located 1,200 light-years away, has a density of just 0.059 grams per cubic centimeter. That's roughly the same as cotton candy.

  1. The Magratheans offer an optional meringue crust for their custom planet construction. See, Douglas Adams knew the truth!

  2. Well, it’s obvious how it can exist. Because my niece hasn’t gotten her sticky little fingers on it yet.

  3. apparently a black hole the size of the observable universe (or entire universe i forgor) would be as dense as, air, lol.
