Next time you worry your collecting habit is getting a bit out of hand, you can try consoling yourself with the knowledge that the sun is a bit of a collector, too.
But, rather than hoarding comic books (guilty as charged), baseball cards, vintage trainers, or Pokémon cards, the sun snatches up passing rogue planets — and it isn't picky. The sun is capable of grabbing small planets as well as Jupiter-size gas giants that get too close; our star then keeps them at the edge of the solar system.
As any collector will tell you, one of the key parts to any collecting hobby is trading — and the solar system does this, too.
