Will any spacecraft visit at least 3 astronomical bodies other than the Earth or Sun before 2040?

Question

So far the record is two, by the Dawn spacecraft.

Specifically, it must decelerate to the point where it's not on an escape trajectory from that body. The body must be large enough that it can feasibly be orbited.
