Impact rates on Jupiter and Earth compared. Vertical gray regions represent the sizes of the three bolides discussed in this work. The blue box represents the impact rate of 5−20 m size objects in Jupiter. Lines represent impact rates from dynamical models of comets (red line with estimated uncertainties in dotted line, Levison et al. 2000) or the cratering record in Galilean moons (blue line, Schenck et al. 2004). The yellow regions indicate limiting size of objects that could be discovered by the dark debris they should leave in Jupiter’s atmosphere. The small SL9 N fragment would only be observable for a few planetary rotations at the resolution attainable with the HST. A long-standing debris feature is probably associated to objects of 200 m in size such as SL9 fragment D. The light-brown box represents estimates of impact rates on Jupiter from Sánchez-Lavega et al. (2010) for 0.5−1 km size objects. The green box represents objects leaving debris field that could be detected with amateur equipment.
