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 our Solar System. Voyager 2 will also eventually leave the Solar System. It reached Neptune in 1989: what was the escape velocity needed to break free from the Solar System's gravitational field there?Explanation / Answer
Escape velocity required to escape out of solar system from Neptune is 7.7 km/sec
Escape velocity is the minimum speed required for an object to escape from the gravitational influence of a massive body. escape velocity actually depends on where we start. Here the voyager reached Neptune and from there the space probe will break free from teh solar sytem. From neptune to break free from solar system the escape velocity required is 7.7 km/sec
