Scientists have been monitoring and calculating the likelihood of a potentially disastrous asteroid collision with the Earth in the year 2182. The asteroid, (101955) 1999 RQ36, is only estimated to be a one-in-a-thousand chance that it will collide with the Earth, but as scientists have calculated the potential impacts through the year 2200, over half of the calculations point to the year 2182 for a collision.
The mathematics behind the calculations come by using two different models, the Monte Carlo Method and line of variations sampling. Using these models, VIs (Virtual Impactors) have been searched. VIs are sets of uncertainties that would lead to collisions with the Earth, two of which appear in 2182 with over half the chance of an impact.
The asteroid is part of a group of Potentially Hazardous Asteroids (PHA), which all have the possibility of colliding with the Earth and causing damage because of the proximity of their orbits. The asteroid in question was discovered in 1999 and has roughly 560 meters in diameter.
