When will meteor 2018LA hit earth?
It will collide with earth on Sun, Jun 3, 2018, which is - days and - hours from now.
Theoretically a meteor impact should only happen once or twice a century. The reality is however that given the incompleteness of the near-Earth-object (NEO) catalogue, an impact could occur at any time. There are thousands of NEOs larger than 140m still to be found.
