1. Find asteroid at L1 Lagrange point, which is unstable, meaning objects need to burn fuel to stay there for prolonged periods of time
2. Put giant sunshade on it directly facing the Earth
3. Sunshade acts like the largest solar sail in existence, making station-keeping useless
4. Because L1 is an unstable equilibrium, solar radiation immediately blows asteroid away from the Lagrange point and directly into Earth’s gravity well

I’m sure nothing can possibly go wrong with this plan.
