With the size of the asteroid, is this one where we could use the gravity tractor[1] or the Yarovsky Effect[2] techniques for deflection, or is there not enough lead time?

To change orbit of so large asteroid, need huge amount of energy.

Unfortunately, humanity now have only small power ready, for such far things just about 50kW, it will need decades to transfer so large energy.

Russians claimed to create nuclear reactor for space with somewhere near 200kW, but unfortunately, now these are just words, very far from real hardware.
