To escape the Earth’s gravitational influence you need to have a certain escape velocity (even if you are the superman), you must fly up towards space with approx. 40,320 km/h, however, a speed of 42.1 km/s is required to escape the Sun’s gravity (and exit the Solar System) from the same position. But what if…
