Speed Required for Spacecraft to Exit the Solar System

To escape the Solar System, a spacecraft must reach a speed of about 42 km/s relative to the Sun, which is achieved by some of our fastest probes like Voyager and New Horizons. Achieving this requires overcoming Earth's gravity and orbital mechanics, and only a few spacecraft have successfully left the Solar System so far.
