The afterglow resulting from the planetary collision, as described in the study, took approximately 2.5 years to disrupt the typical starlight emitted by ASASSN-21qj.

There are other challenges. Unlike Dimorphos, 2015 XF261 doesn’t orbit a larger asteroid, so if it is deflected by the spacecraft, it isn’t clear which trajectory it will wind up following.And ...
