Second day at #PDC2025. We are discussing today the results of the #SMPAG impact simulation exercise, which has extended from last August until a couple of weeks ago. It has been an amazing exercise!

What a fantastic week we have had in Stellenbosch for #PDC2025! You can really sense how much #PlanetaryDefense has advanced in the last years and how many people is now involved in it!
Looking already forward for #PDC2027 in #Montreal!!!

When addressing the impact hazard, we have had only one DART.

Steve Chesley describes the heliocentric orbit change for Didymos from the #DARTMission impact, rather that the orbit change of Dimorphos about Didymos.
~12 microns/second, measured by occultation timing.
Lots of science from chasing shadows.

#PDC2025 reviews the impact of satellite streaks on the asteroid discovery surveys.
They continue to be a nuisance; but are manageable. And they remain concentrated into twilight data where detections were already tricky.

Davide Farnocchia reviews #2024YR4:
63 observatories, >500 observations.
3.8% chance of lunar impact in 2032 December, with the last observations for this year still pending.
It will likely require waiting until 2028 to resolve the lunar impact possibility. But it cannot impact Earth.
