The last time man set foot on another celestial body was in December of 1972 when the Apollo 17 mission landed on the moon. Since then, the space race has shifted to more martian and extra-terrestrial terrain. While it looks like humans might be going to the moon again and even Mars in the near future, another celestial exploration question remains… could we ever explore another star?
Right now, the only star we have explored in some detail is our own Sun. The problem is, the next nearest star isn’t exactly close to our home planet.
The furthest man-made object away from earth right now is the Voyager 1 spacecraft, which is 140 astronomical units away from earth, or 140 times as far away from earth as the earth is from the sun. This distance is massive, but one problem remains. At current rates of speed, it would still take 73,000 years to reach the next nearest star. So… will we reach another star in our lifetime? The video below takes a closer look.
