The spacecraft starts moving away from the Earth with the second space velocity. How far will it fly from Earth?

If the Earth were the only gravitating body in space, then the spacecraft would really move away from the planet at an infinitely large distance. In reality, it will remain within the solar system, since the second cosmic speed (11.2 km / s), with which it begins to move, is less than the third cosmic speed (16.7 km / s), with which the object leaves the solar system forever.
