The Local Group (wikipedia)
Our Sun is one of hundreds of billions of stars in a spiral whirlpool of gravitationally-bound suns we call the Milky Way galaxy. The closest
star is 4 light-years, or 24,000,000,000,000 miles (4 * 186,000 * 31,556,926, the number of seconds in a year). To reach the farthest stars of the galaxy, add 5 zeros.
Picture the Milky Way as 100 miles in size. The Sun and its planets would be the size of an eraser on a pencil, the Sun a grain of sand, and you smaller than an atom.
But this is the size of the earth and sun and planets within a galaxy. A single galaxy.
There are a few galaxies near the Milky Way (each separated by unthinkably sparse areas) called "the local group" of galaxies.
And there are many many of these groups
, each with a few or thousands of galaxies. These groups are associated into larger groups called clusters
, with some clusters close enough gravitationally to form superclusters
So when you are irritated at some minor inconvenience, keep things in perspective.
