And now with calculations, using
(1) a = semi-major axis from the SSD Horizons system (date set for today, reference set to solar barycenter) and using (2) v_infinity = square root of ( G * M_sun / |a|) [as per Greg's reference] I get: 16.6 km/s - Voyager 1 14.9 km/s - Voyager 2 12.5 km/s - New Horizons 11.3 km/s - Pioneer 10 10.4 km/s - Pioneer 11 I wonder what Ulysses might have after that rumored Jupiter flyby in 2099 ... Sort of tallies with the values I quoted in my earlier post. Warning though ... I dont do these sorts of calculations for a living, so I may have missed something along the way
