if left undisturbed, "pioneer 10" and its sister craft "pioneer 11" will join the two voyager spacecraft and the "new horizons" spacecraft in leaving the solar system to wander the interstellar medium. the "pioneer 10" trajectory is expected to take it in the general direction of the star aldebaran, currently located at a distance of about 68 light years. if aldebaran had zero relative velocity, it would require more than two million years for the spacecraft to reach it. but well before that, in about 90,000 years, "pioneer 10" will pass about 0.23 pc from the late k-type star hip 117795. this is the closest stellar flyby in the next few million years of all the four pioneer and voyager spacecraft which are leaving the solar system.
