We could move the planet ourselves by building solar sails in hyperbolic orbits that use a gravity assist from Earth to slow down. We do the same thing at the moment with space probes to speed them up - it's all about the angle of the approach.

It's a big planet, but we have plenty of time. If we started relatively soon we could do it slow and cheap.
