I have read articles about the Voyager probes leaving the solar system (or not) depending on what definition is used. So, another definition - do the Voyagers have sufficient velocity to escape the Sun's gravitati0nal influence?

This page gives you an estimated galactic escape velocity relative to the Sun of 550 km/s:SPB COOPERATOR said:Ooops I overlooked the point the the Sun's Ve of 617.5 km/s is from the sun itself, not the solar system. Does the solar system itself have Ve and even the galaxy itself?
Leaving the solar system refers to the act of a spacecraft or object traveling beyond the gravitational influence of the sun and entering interstellar space.
The edge of the solar system, also known as the heliopause, is estimated to be about 123 astronomical units (AU) away from the sun. This is roughly 11 billion miles away.
Yes, NASA's Voyager 1 spacecraft officially left the solar system in 2012 and Voyager 2 followed in 2018. These spacecrafts were launched in 1977 and have been traveling for over 40 years to reach the edge of the solar system.
Once a spacecraft leaves the solar system, it will continue to travel through the vastness of interstellar space. It will encounter different cosmic rays and magnetic fields and may continue to send back data to Earth if its communication systems are still functional.
The amount of time it takes for a spacecraft to leave the solar system depends on its speed and trajectory. For example, Voyager 1 took about 35 years to reach the edge of the solar system, while New Horizons (launched in 2006) is estimated to take about 30 years to reach the heliopause.
