Earth is in the solar system; the solar system is in our solar interstellar neighborhood; our solar interstellar neighborhood is in the Milky Way; the Milky Way is in our local galactic group; our local galactic group is in the Virgo supercluster; the Virgo supercluster is surrounded by other local superclusters, and those local superclusters are all we can observe in the Universe for now.
For additional perspective:
Consider our solar interstellar neighborhood for a moment (third in the chart). Do you realize how far apart the stars are from each other within that neighborhood? If our sun was a marble on Hollywood & Highland, our nearest neighboring star would be a marble in front of Caesar’s Palace in Las Vegas. And the second-nearest neighboring star would be in Alaska. (Something like that.)
