Strange ‘puffy’ alien world breaks every rule for how planets should behave | Astronomers have discovered TOI-4507b, a planet 9x wider than Earth, but only 30 times its mass, giving it the classification of a “super-puff” exoplanet.

TL;DR for its “strangeness”:

>TOI-4507 b is on a nearly polar orbit; it swings around its star almost perfectly perpendicular to the star’s rotation. It has a relatively close orbit, completing an entire revolution in just 105 days — but this also makes it one of the longest-period super-puffs ever found. So we have a low-density, puffy planet orbiting relatively far from a young star in a nearly perpendicular orbit.

What has the universe become, now even planets don’t behave any more.
