Quoting: Anonymous Coward 33702759 Watch please! If we 'observe' it, it could change its trajectory?? WTF Quoting: Anonymous Coward 33702759 That was an excellent explanation of how we determine and refine the orbit of an object. As we observe it over time, we improve our determination of its orbit and lower the uncertainty in the orbit. If the region of uncertainty overlaps earth, then there is a risk of impact. It does not overlap earth in this case.
