Life on Mars and Solar System Moons: The Search for ET LIfe in our Own Backyard

This audiobook is narrated by a digital voice.

Alpha Centauri is the nearest star to the Sun, located 4.4 light-years away, and is one of the most promising locations for the search for extraterrestrial life. Alpha Centauri constitutes a trinary system. Component C is an unremarkable red dwarf, whereas component B is marginally cooler and dimmer than the Sun, and component A is nearly a duplicate of the Sun. A and B orbit one another with a minimum distance of eleven AU, and models indicate that this will not disturb the orbits of any planets located within two AU of either star.
