Star travel is the ultimate dream of visionaries . . .
Yolanda, the closest star to our sun is a triple star system called Alpha Centauri. There's a lot of space between us and this star. If you imagine Earth as small as a grain of sand, then Alpha Centauri would be over six miles away. Light from Alpha Centauri takes four years to travel to Earth . . . Let's imagine you could send a whole colony of people to Alpha Centauri.
