How to stop an asteroid from hitting Earth without nukes?

+0
−0

You are in charge of the world, with technology about the same as we have now, except that a while back the leaders of the world decided that nukes are too powerful, so they destroyed them all and noone knows how to make them anymore.

The space program has also died out, so you do not have any probes.

When some astronomers tell you that there is a large asteroid coming in 5 days and the impact will kill all human life on Earth, what do you do to prevent the impact?
