how long will it take them to travel 4.2 light years- the distance to the nearest star?
Please show me your calculations...

We'll use English units, just to be different.
Pluto's orbit is highly elliptical; the average distance is about 40 AU. One AU = 93 million miles, so the Voyagers are about
( 2 ) ( 40 AU ) ( 93,000,000 miles / AU ) = 7.44 x 10^9 miles from the Sun.
4.2 Light-Years = ( 4.2 light-years) ( 5.88 x 10^12 miles / light-year ) = 2.47 x 10^13 miles.
The fraction of this distance that has been covered by Voyager is
7.44 x 10^9 miles / 2.47 x 10^13 miles = .003 = 1 / 3300
So they need ( 3300 ) ( 30 ) = 66,000 years to travel 4.2 light years at their current average speed.

No an area craft in no way did. Uranus is a gas significant and it does not have a floor. in basic terms Voyager 2 handed Uranus yet in no way landed. the only area crafts that handed are telescopes.

You do know that none of the Voyagers are going directly to any star in particular including the Proxima Centaura.

First of all, they aren't headed to the nearest star. But if they were, it would take 8 to 10 thousand years.
