#FICTIONALEVENT

As observations continue, the likelihood of an Earth impact in 2027 is increasing. 3 weeks after discovery, after observations had to be paused during the full Moon (and reduced visibility), the chance of impact has risen to 1 in 250 #FICTIONALEVENT #planetarydefensepic.twitter.com/MlNd9VX06K

#FictionalEvent First press release on asteroid #2019PDC The International Asteroid Warning Network has announced a worrying discovery: a near-Earth asteroid 100-300m in length has a 1/100 chance of striking Earth in 2027 Find out more: http://blogs.esa.int/rocketscience/2019/04/25/hypothetical_impact/ … #PlanetaryDefensepic.twitter.com/C06oUxOFDi

#FictionalEvent Update on (fictional) asteroid #2019PDC 29 July, 2019 - Chance of impact has dramatically increased to 1 in 10 - Size estimate has been narrowed to 140-260 metres - Earth impact could release 100-800 megatonnes of energy #PlanetaryDefense #ExerciseOnlypic.twitter.com/guFUzxm9NO

Final update on #FICTIONALEVENT: 19 April 2027 The 60-m fragment of fictional asteroid #2019PDC is predicted with certainty to impact over the Central Park area in New York City, 10 days from now #ExerciseOnly!! #PlanetaryDefensepic.twitter.com/g7AcucI9WE

Find out how this dramatic & risky situation will turn out LIVE from this year's #PlanetaryDefense Conference, starting Monday, 29.04. During the week, we'll post live updates the moment the experts are informed. What will they decide? #FICTIONALEVENT #ItHappenedBeforepic.twitter.com/3y7WTXlOyK

#FICTIONALEVENT is a fun hashtag to follow at the moment. pic.twitter.com/p56Td5rziA

#FictionalEvent Specialists have modelled the likely effects of an impact of this size on Denver and the surrounding area, population almost 3.5 million #ExerciseOnlypic.twitter.com/wMZiaHp4Bl

#FICTIONALEvent 30 Dec 2021:Update on #fictional asteroid #2019PDC A reconaissance spacecraft was sent to the asteroid to find out more about its path, revealing its on a certain course to impact Denver, Colorado on 29April 2027, the International Asteroid Warning Network revealspic.twitter.com/dCnGkgamgQ

Very little is known about the asteroid’s physical properties. From its brightness, experts determine that its size could be anywhere from 100-300 meters - about 5-15x bigger than the 2013 #Chelyabinsk impactor #FICTIONALEVENT #PlanetaryDefensepic.twitter.com/xWTVbSPMZn

Join us tomorrow at 14:00CEST (08:00EDT) LIVE on Facebook from this year's #PlanetaryDefense Conference. We'll discuss the impact scenario/#FictionalEvent with Kelly Fast and others. What will happen next and what have we learnt so far? Tune in! http://www.facebook.com/europeanspaceagency …pic.twitter.com/MoVPQYmCRr

It’s 2028, and ESA has been carefully monitoring a worrying situation: an enormous asteroid is en route to strike Earth, although the exact point of impact is not yet clear... To find out what happens next in this #FICTIONALEVENT, follow @esaoperations #PlanetaryDefensepic.twitter.com/K6OxzOOr4R

#FictionalEvent Earth impact is (hypothetically) certain. The exact location is not known, but the Eastern United States and Atlantic ocean are at risk. pic.twitter.com/pxri27n8aL

#FictionalEvent Three more months of observations from around the world have refined our understanding of asteroid #2019PDC's orbit, which now has a 10% chance of striking Earth. Experts are performing detailed risk assessments to understand the potential impact effectspic.twitter.com/R4z4fdo5sj

#FictionalEvent A rendez-vous reconnaissance mission would provide us with much needed information on the asteroid's size and composition. It could arrive at the asteroid by 2022, (5 years before possible impact) #ExerciseOnlypic.twitter.com/ERzDQh14uY

Have you been following this year's #FictionalEvent at the #PlanetaryDefense Conference in Washington DC? A 60-m fragment of (hypothetical) asteroid #2019PDC is headed straight for New York, and evacuations are under way. Now: Discussions, recommendations and lessons learntpic.twitter.com/ja6Lomf3zN

#FictionalEvent Paul Chodas, manager of NASA's Center for Near-Earth Object Studies #CNEOS, who designed this year's scenario says: "We have the resolve, we have a space programme, we can prevent this"pic.twitter.com/YpEumRe4co

#FictionalEvent The small (fictional!) asteroid #2019PDC will enter Earth’s atmosphere at 19 km/s (43,000 mph) on April 29, producing a large fireball or “megabolide,” and predicted to release 5 to 20 megatons of energy in the airburst.pic.twitter.com/EpiQS1JwGb

#FictionalEvent Initial observations suggest asteroid #2019PDC could hit anywhere under the dotted red line, or "risk corridor" #ExerciseOnly #PlanetaryDefensepic.twitter.com/9XSwtIHS6q

#FictionalEvent The goal is to break the asteroid remnant into smaller peices before it impacts Earth, each of which will then be small enough to break up in our home planet's atmosphere. #PlanetaryDefense Perseidspic.twitter.com/DjQGjwZ01f
