Question

In 1977, NASA launched two unmanned space probes, Voyager 1 and Voyager 2. These probes visited the four gas giant planets, traveled through the outer Solar System, and are now on their way out of the Solar System. In June 2012, NASA announced that Voyager 1 is very close to entering interstellar space and becoming the first man‑made object to leave the Solar System.

Voyager 2 will also eventually leave the Solar System. It reached Jupiter in 1979. What was the escape velocity needed to break free from the Solar System's gravitational field there?

Answer 1

Calculation is showing if probe is going away from the Sun, it will require less escape velocity.
