Pokemon GO is one of the few unique mainstream games that rewards players for going out into the real world and exploring. Whether they’re walking down the block or across their entire city to hatch eggs, Pokemon Trainers the world over have racked up quite the tally – over 9 billion KM have been tallied by trainers the Pokemon Company since its July launch.

If you need a comparison to help you comprehend just how massive 9 billion KM is, here is what the Pokemon GO blog said:

“We are pleased to share that—as of December 7—the Pokémon GO community has collectively walked more than 8.7 billion kilometers. That’s more than 200,000 trips around Earth! Fun fact: A commercial jetliner would take more than 1,000 years to cover the same distance. While covering this distance, Trainers also caught more than 88 billion Pokémon along the way. That’s roughly 533 million Pokémon a day!”

Even with all of this walking, Pokemon GO Players haven’t crossed the entire solar system yet – who knows if Nintendo will make an interstellar announcement once players cross the 287 billion KM mark (the diameter of our solar system).
