For a week or so after its discovery by the 3.5 meter Space Surveillance Telescope, 2015 PU228 was thought to be the asteroid most likely to collide with Earth in this century. Calculations based on limited data indicated that this asteroid had a one in 23,000 chance of colliding with our planet in January of 2081. As the length of 2015 PU228's observed path in the sky grew its chances of a collision with Earth decreased. More than a month's observations has made us sure that it will completely miss planet the Earth in 2081.
