Detection codes:

A: atmospheric debris observed
C: crater (or craters) resulted
I: infrared sensors (for Earth impacts, satellite-based sensors)
M: meteorites recovered
O: observed visually
P: predicted (impacting object was discovered and orbit determined prior to impact)
S: infrasound detection
V: optical sensors (for Earth impacts, satellite-based sensors)
#: impact not observed, but impact constrained to a period of a few months by successive satellite imagery
*: no destructive impact, but object left atmosphere and remained in solar orbit
