This says that the trajectory was affected[1]:
> On Sept. 26, DART crashed into Dimorphos at a speed of 6.6 kilometers (4.1 miles) per second. The impact should have changed Dimorphos' orbital period around Didymos from 11.9 to 11.8 hours — a difference of just 4.2 minutes. This will pull Dimorphos slightly closer to Didymos.
