Post-impact observations from Earth-based optical telescopes and planetary radar would, in turn, measure the change in the moonlet's orbit about the parent body.

Simulations carried out by leading space agencies have concluded. There currently is no technology available that could stop a massive asteroid from "wiping out" Europe.

LOS ANGELES - A group of scientists and experts, at NASA’s behest, spent a week attempting to stop a fictitious asteroid from crashing into Earth and failed.
The scientists were invited to a week-long tabletop exercise led by NASA in which they were instructed to use all of Earth’s technological advancements, which were hypothetically at their disposal, in order to stop the space rock from hitting the planet.

Asteroid That Hit Botswana in 2018 Likely Originated From Vesta

An international team of researchers searched for pieces of a small asteroid tracked in space and then observed to impact Botswana on June 2, 2018. Guided by SETI Institute meteor astronomer Peter Jenniskens, they found 23 meteorites deep inside the Central Kalahari Game Reserve and now have published their findings online in the journal Meteoritics and Planetary Science .
With asteroid defense, Iowa State research could come into play
There's not always a stable trajectory for funding of research on how to push an asteroid away from a potential collision with Earth, but an Iowa State University researcher said that's actually not that much of a problem — provided there's enough advance warning to do something if a threat does emerge.
Bong Wie has some agreement on that. While Wie said an impact is "one of the only natural disasters which can be prevented," the chances of it happening are so small, the "best solution is doing nothing," for now, when it comes to deflection research.
NASA simulation reveals the "best defense" against an asteroid impact
On April 19, telescopes on Earth detected a huge asteroid out in the depths of space whizzing along at 11,000 miles per hour toward our planet.
Simulated trajectories estimated it could crash down somewhere in the Americas, Europe, or Western Africa in October. Initial observations suggested the object could be bigger than a skyscraper — large enough to obliterate major cities in its path, like New York, London, or Lagos.
You likely didn't hear about this menacing space rock until now — because it doesn't exist. In truth, it is part of a fictional scenario fed to a global team of experts who gathered virtually last week for the annual International Academy of Astronautics Planetary Defense Conference Exercise . During a four-day drill, more than 300 participants from the U.S.
Asteroid that traveled 23 million years to get to Earth discovered | TweakTown
Back in 2018, astronomers watched an asteroid approaching Earth, and only a few hours later, they tracked the landing to Botswana.
The asteroid named 2018 LA began to break up as it entered Earth's atmosphere at 38,000 miles per hour. A group of researchers managed to find 23 fragments of the asteroid in Botswana's Central Kalahari Game Reserve, and according to the study from the group, the asteroid fragments actually came from the brightest and second-largest asteroid in our solar system named Vesta.
Ejecta distribution and momentum transfer from oblique impacts on asteroid surfaces
NASA's Double Asteroid Redirection Test (DART) mission will impact its target asteroid, Dimorphos, at an oblique angle that will not be known prior to the impact. We computed iSALE-3D simulations of DART-like impacts on asteroid surfaces at different impact angles and found that the the vertical momentum transfer efficiency, β, is similar for different impact angles, however, the imparted momentum is reduced as the impact angle decreases.

New Project Aims To Improve Planetary Defense Against Asteroids – Eurasia Review
The University of Alicante (UA) is once again participating in a project on advanced research on near-Earth objects and new technologies for planetary defense that will run up to 2023. The project, called NEO-MAPP (acronym that stands for Near Earth Object Modelling and Payloads for Protection), is made up of 15 European institutions and funded by the European Commission with €4 million in the 2019 H2020 call for proposals.
According to Adriano Campo Bagatin, a researcher at the UA’s Department of Physics, Systems Engineering and Signal Theory, the scientific community has become aware of the need to measure the current technological capacity to avoid asteroid collisions with the Earth and to search for protective devices against this potential risk in recent decades.
