16 Psyche is far to big to move anywhere.

16 Psyche's mass is 2.27·10^19 kg and its orbital speed is 17.34 km/s.

Earth's orbital speed is 29.78 km/s.

So a perfect orbital transfer (not even possible) to get 16 Psyche into Earth's orbit would take an impulse of at least (29780.0 m/s - 17340.0 m/s) · 2.27·10^19 kg = 2.82388·10^23 kg·m/s.

A Saturn V rocket produces 3.51·10^7 N of thrust.

So it would take one Saturn V rocket 8.0452·10^15 seconds to move 16 Psyche, or 2.5511·10^08 years.

If we had 1 million Saturn V rockets, it would take just over 255 years.
