Wolf 359 is a red dwarf star located in the constellation Leo, at a distance of approximately 7.9 light years from Earth. A high rate of proper motion can indicate that a star is located nearby, as more distant stars must move at higher velocities in order to achieve the same rate of angular travel across the celestial sphere. But since even the nearest stars are hundreds of thousands of times farther away than the diameter of Earths orbit, the parallax shifts are tiny, and can only be measured with precise instrumentation.
