Predictions of impacts per year on Jupiter that leave observable debris fields, and their detectability.

Size (m) Mean Min Max Detectability
(yr−1) (yr−1) (yr−1) (yr)
45 2.8 1.1 7.0 0.4–2.6
170 0.43 0.17 1.1 2–12
380 0.15 0.06 0.37 6–30

Notes. The impact frequency is the number of impacts that we estimate to occur on Jupiter every year. Their detectability (the mean number of years between observable impacts of a given size and larger) is affected by observational biases, as discussed in detail in Sect. 7.3.
