The view will expand in each step by some factor of about 10 in distance up until we get to the limit of the edge of the universe. This is when you enlarge the view by another factor of 100 and see a region 1,000,000 km wide. Numbers start becoming too large to write them out: this is were scientiic notation and au come in and help astronomers deal with large numbers, the entire solar system. This includes major planets and slightly elliptical orbits.
