> let’s say just couple of years ? Not a couple of years. The Voyagers have been doing around 38 000 mph since the late 1970's. That is rougly 17 km/s.

It will take it decades to overtake any of them (no actual overtaking will probably take place though, as its trajectory most likely will be different).
