- flexie 6y agoThen how can they say 1-20% risk of collision?
- LoSboccacc 6y agoprob they can measure speed at a higher accuracy than one mm/s, also orbit have a relatively low inclination difference and objects have a size, so that the impact area is not a point but a larger ellipses of varying overlap between bodies.
