The ship salesperson is also a liar. He/She/It couldn't be from Alpha Centauri as its a triple star system orbiting around their combined center of gravity. Any planet that formed, of substantial size, would be in an unstable orbit (due to the other two stars's gravitational influence over time) and would be flung out into interstellar space. Perhaps a small mercury sized planet could form, but it would have to be very close to its stellar parent, too small to retain an atmosphere and bombarded by it's radiation. Not exactly ideal conditions for life to get a leg up (let alone a leg). End of science lesson for today. BTW very cool space ship. Thank you!
