Sir we've detected a signal

What would we do if we detected an apocalyptic asteroid coming towards earth? Well we detected something out by neptune, it's going to take about 30 years to travel the vast distance from Neptune to Earth, but when it arrives that's it, game over, sayonara, arrivederci.

Do you think you can save earth? Launch rockets, plan orbits, manage resources and divert the incoming apocalypse.
