Asteroid simulation no Apophis

[Felix Hana]

I have opened the simulation “Potentially hazardous Asteroids” and there are many objects flying around but one is missing Apophis. That seems kinda weird to me cuz it comes very close to Earth in 2029 and even closer in 2036. Officially the risk of impact seem really very low in 2029 and very low in 2036. However, still seems it’s one among all dangerous objects with the highest impact risk.

In few words that seems really fishy. Apophis can easily be found under minor objects but missing in that simulation. May it be cuz if you are running the simulation with Apophis it will nearly always hit in 2029 or 2036?

I can’t believe they simple forgot it cuz there are quite a few documentaries about it analyzing the risk and cospiration videos that show it will hit for sure. Also it can be found like said before easily under minor which suggests to me the risk is real.

What do you think about it?

In both cases where Aphophis passes close to the earth, measurments of impact probabily say it will just pass right by earth. When it was discovered in '04 it was initially predicted to have 2.7% chance of hitting the planet, which is pretty low, since then the small rock has been studied much more thoroghly and more prescise measurments have been taken to project its course.
My guess as to why you don't see it in the simulation is due to a few factors.

1.) Only so many attracting bodies can be placed in the sim before slowdown effects systems, they may have wanted to make sure that people with slower machines could view the sim and left some bodies out on purpose.

2.) Aphohis is quite small, and the number of "Potentially Hazardous" objects is quite large. There are quite a few asteroids that are close to 1 km in size that would be cause more catastrophic effects than aphophis which is around 210-330 meters in size. this is the differnce between a "Planet Buster" and "City/Country Killer"

3.) The simulation may not be designed to show "Close Approach" asteroids, those that are expected to pass very close to the planet, only the ones that could potentially be a problem do to their size and proximity to the planet. There is a list of these Close Approach type of asteroids here: NEO Earth Close Approaches [cneos.jpl.nasa.gov] if you set the table to show you Future only and set the H limit setting to <=26 you should get a long list of close approach rocks that are expected to get within 0.05 au of the planet. The count when I did this search was 515 objects. These are only the objects with a high degree of certainly they will pass by us there are quite a few more that NASA is not certain about.
