FAQ
Reader questions
What defines an FT3 asteroid in current classification systems? FT3 refers to a specific risk threshold and object size band used for impact monitoring, not a single object, combining kinetic energy and probability metrics. How often are FT3 object orbits updated by monitoring centers? Orbits for FT3 objects are typically updated weekly or after new observational data, with major revisions triggered by close approach campaigns. Can an FT3 classified asteroid cause regional damage if it impacts?
Yes, depending on size and energy, an FT3 asteroid could cause regional damage, motivating continuous tracking and international mitigation planning.
What role do amateur astronomers play in FT3 monitoring?
Amateur astronomers contribute follow-up astrometry, helping refine orbits for newly detected FT3 class objects before professional campaigns intervene.
