Narrative:

En route from XXX airport to YYY airport, I had to go past 2 nuclear power plants. I visually checked my distance and thought I was 10 miles away out of the class C airspace at ZZZ. When I landed I was told to call ZZZ tower. I was told I was 5 to 7 miles away from the plants. In the future I will get flight following from ZZZ. I assumed I could tell the distance to the plants, but was off.
