Roughly how many comets per year are typically visible to the naked eye for a casual observer?
Answer
Roughly one comet per year
The frequency of comet sightings depends heavily on the required visibility threshold. While the inner solar system is continuously populated by countless icy bodies that diligent observers with good equipment can detect year after year, the casual observer's experience is different. Generally, estimates indicate that only about one comet annually manages to achieve sufficient brightness and proximity to become visible without optical aid. However, these annual visitors often present as merely fuzzy patches and may not qualify as truly memorable or spectacular displays.
