How often is the Target Asteroids! list updated?

The Target Asteroids! team will update the list as needed. If new asteroids that meet the criteria for our program are discovered, they will be added to the Target Asteroids! list. No objects will be deleted from the list though some may be downgraded in priority as we learn more about them. When updates occur, we will send out a notification to the Target Asteroids! listserv (members include those participating in the Astronomical League’s Target NEOs!).
