SUMMARY
The Voyager probes, currently traveling at speeds of 38,000 mph (17 km/s), are significantly below the third cosmic velocity of 42 km/s required to escape the Sun's gravity well at Earth's orbit distance. Voyager 2 is even slower than its counterpart. The escape velocity is contingent upon the spacecraft's position within the gravitational field, and at their current locations, the Voyagers will not achieve escape velocity but may enter large elliptical orbits. A graph illustrating Voyager 2's velocity compared to escape velocity is available on its Wikipedia page, alongside a simulation tool for visualizing hyperbolic trajectories.
