The article discusses the possibility of interstellar exploration to the Alpha (α) Centauri system based on humanity's current level of technology and interest, and describes the history of travel beyond the Earth. The nearest star to the Sun is the red dwarf Proxima Centauri, but it has no known orbiting planets. Astronomers discuss nuclear fission versus fusion powered spacecrafts, the heath of people traveling in space, and the cost of constructing and maintaining the craft.
