Distance

The Nearest Star website gives some perturbing information:

Proxima Centauri is the nearest star to our Sun, at 4.22 light years away. This means that Voyager, travelling at 38,000mph/ 61,000kph would take 73,000 years to reach the star.

The fastest space craft is the Helios 2 solar probe, at 157,100mph/ 252,800 kph. So if Helios 2 went to Proxima Centauri it would still take 17,633 years.
