On simulated time April 26, the team discovered an asteroid 35 million miles (57 million km) from Earth, with a 5 percent chance of impacting the planet on or around October 20, 2021. Based on its mean apparent visual magnitude, the asteroids absolute (intrinsic) magnitude is estimated to be H = 22.4 +/- 0.3. Instead, the space agencies have settled on targeting Asteroid 25143 Itokawa as part of their Double Asteroid Redirection Test. The 2021 PDC Hypothetical Asteroid Impact Scenario, Day 2, showing the possible impact range.

The point at which the orbits The NASA Jet Propulsion Laboratory's Centre for Near Earth Object Studies (CNEOS) is coming to the end of a week-long "wargame" to help define its response to a real asteroid impact threat in . Both systems agree that the most likely potential impact occurs on October 20, 2021 - just 6 months away - but the probability of that impact is low, about 1 chance in 2500. A larger object would appear brighter in infrared light, and this measure isn't affected by albedo.

NASA has identified an asteroid, named by astronomers as "2021PDC," with a one in 20 chance of impacting on Central Europe on or around October 20, 2021.. Luckily, 2021PDC is only a simulation. It will reach a minimum distance of around 2 million miles (3.2 million km) from Earth. The scenario begins as follows:An asteroid is discovered on April 19, 2021, at apparent magnitude 21.5, and confirmed the following day. Detailed maps of the Earth, showing a huge potential impact area were shown to the team. On the other hand, an asteroid with a charcoal-like surface will reflect less light, and could therefore appear smaller than it is. . #20OCTOBER2021 #ASTEROID #NASA #ASTEROID2021PDC #2021PDC #HYPOTHETICALASTEROID The 2021 PDC Hypothetical Asteroid Impact ScenarioAlthough this scenario is re. Both systems agree that the most likely potential impact occurs on October 20, 2021 - just 6 months away - but the probability of that impact is low, about 1 chance in 2500. until just before the October encounter, since the asteroid will remain too far away for detailed observation for that entire time.
