1990 MU asteroid from the "Apollo Group'

On 8th June 2027, an asteroid titled 1990 MU with its size comparable, apparent measurement of over 3 kilometers, to Mount Everest, is on a eccentric orbital flyby with the Earth.  It is classified a potentially hazardous asteroid, discovered in 1990, the rating system of how an asteroid poses a threat is scaled by its predicted distances from the Earth, moon and the magnitude of brightness, reflected by the Sun's light.  1990 MU is therefor seen as one of brightest and largest asteroids from the infamous Apollo group.  Most of these  larger asteroids have been calculated via a deterministic measuring system that monitors these orbits into the next 50 years.  So far, a comprehensive list has been made of the larger potentially hazard Near Earth Objects (NEO) of the Apollo group which includes some comets, that are orbiting within our Solar System. 

However, there is an uncertainty principle and this is where the Yarkovosky effect comes into play, discovered by the Polish Civil Engineer Ivan Osipovich Yarkovsky in 1900, who was also a hobby scientist.  Wrote a pamphlet of the same year of his discovery that heating of a rotating object in space would, no matter how small the effect would be, could, over its deterministic course, alter the trajectory of these objects, namely asteroids.  In other words, a shift from an calculated orbit of its possible deterministic trajectory into an uncertain and potentially hazardous one if, the Minimum Orbit Intersection Distance (MOID) is already decreasing, this could hypothetically, in a chaotic sense. Lead to a strike on th Earth from one of these larger Near Earth Objects. 

With digital podcasts, half baked tabloids and billionaire man child/s all throwing around tediums within the sensationalism of the potentiality of a hazardous strike on the Earth from Space, this is where the importance of ground and space telescope satellites are essential in monitoring NEOs more so, to calculate the various unobservable effects that may alter trajectories; from light radiation, gravity shifts and collisions with other asteroids, all these trajectory changes which may shift the orbital deterministic modeling into a far more deadly angle.  More so, there must be limit to the amount of space junk placed into the lower and upper atmospheres, this is important because, yes, we may be able to map and study the larger groups of asteroids, but, astronomers can and have missed smaller objects.  If the skyline is littered with small bright pieces of man-made objects intended for faster social media uploads, this may cloud a smaller/medium on course with the Earth.
