The New Horizons spacecraft is unmanned; it will be visiting our solar system's Kuiper Belt on January 1, 2019. This may reveal aspects of a similar belt in the the Proxima Centauri star system. Proxima b, the only planet identified with Proxima Centauri, is estamated at about 1.3 times as large as Earth and completes one day per (Proxima b) year; that is, it revolves around Proxima Centauri as Mercury revolves around the Sun, the same side always facing the star. Of couse, for a more direct analysis, our spacecraft could visit the Proxima Centauri star system, itself; traveling at the speed of light, it would be there in slightly over four years.
By current Terran standards, for a more worthwhile trip, is the locale of the GW170817 kilonova neutron star merger which created 50 Earth masses worth of silver, 100 Earth masses of gold and 500 Earth masses of platinum. This must be great news for those of you with a self-space-mining spacecraft; hurrying there at light speed, you can be there and back in about 260-million years. You may not be in any condition to do anything with your cargo but, hey...
