You can look up escape velocity which is the velocity required to exit a gravitational body completely.
That’s also what makes getting to the sun so difficult. At first you got to speed up to escape velocity to escape the Earth’s gravitational pull, then you enter an orbit AROUND the sun, where you will have to slow down by a lot to lower your orbit enough to get into the sun. Miscalculate and you’ll fling yourself out of the solar system.
