it initially carried a 2.7% chance of impacting Earth during its 2029 flyby – then a record. While YR4's impact odds have unseated Apophis, the larger asteroid still briefly hit a higher rating ...

A similar scenario unfolded in 2004 with Apophis, an asteroid initially projected to have a 2.7% chance of striking Earth in 2029. Further observations ruled out an impact. NASA did note ...
