The 2021 PDC Hypothetical Asteroid Impact Scenario, Day 2: April 27, 2021
This image shows the current predicted impact region for 2021 PDC. There is a 99% chance the impact will occur within the boundary of the entire shaded region; the boundaries of the two inner shaded regions indicate other probability levels: the chance of impact is 87% inside the middle contour, and 40% inside the central dark-red region.
A Google Earth kml for this predicted impact region
is available here.
