This Earth crossing asteroid is being eyed for potential mining operations:
As of May 2018, according to the Asterank website, operated by Planetary Resources, the current value of Ryugu for mining purposes is speculated to be US$82.76 billion, and the chemical composition of the asteroid is claimed to be of nickel, iron, cobalt, water, nitrogen, hydrogen and ammonia.
Try to imagine getting planning permission (from whom?) to alter the orbit of an asteroid such that, in a few years time, it gently comes up on the Earth from behind and can then be nudged into a stable orbit for nearby resource extraction. Imagine the Chicken Little reaction from luddites everywhere. Might be better to extract the useful material out there in the distance, and shoot smallish chunks of it towards the Earth/Moon for capture. Makes a smaller Kaboom! if you miscalculate.

.
I have a little dreidel
I made it out of clay
And when it's dry and ready
Then dreidel I shall play.

Oh, dreidel, dreidel, dreidel
I made it out of clay
Oh, dreidel, dreidel, dreidel
Now dreidel I shall play.
