The document discusses distances in our solar system and galaxy. It provides average distances between Earth and other planets and objects like the Moon (238,000 miles) and Sun (93,000,000 miles). It also defines units like the astronomical unit (AU) and light-year, which is used to measure distances to our nearest star systems like Proxima Centauri and Alpha Centauri (4.2 and 5 light-years away) as well as the size of our galaxy (diameter of 100,000 light-years) and local group of galaxies (2 million light-years).
