Planet 9, the hypothetical planet predicted Batygin and Brown, is expected to have an apoasis near the galactic center. Is there a spacecraft that is heading in that direction? Specifically, they state:
perihelion position is straight overhead in late May. ... aphelion (the furthest point from the sun) at about 4 hours, or straight overhead in late November
Note that I realize that we don't know where this object is, and thus would have great difficulty pinpointing this exactly, but are any of the known objects leaving the solar system heading in that direction?
Also, of some note is that the inclination is expected to be 30 degrees, plus or minus 20 degrees.
