Planets with more mass are harder to escape than planets with less mass. ... As an object moves away from the planet, the planet's gravitational pull will have less of an influence on it. If the object moves far enough away, it feels almost no attraction. When this happens, the escape velocity will basically be zero!
Why do different planets have escape velocities?
Escape velocity depends on the mass of planet. The heavier the planet the greater is its graviational pull on the object and more difficult for it to escape. We know that planets are bigger and smaller. So their escape velocities are different.
Can a bullet escape the atmosphere?
Even a bullet, fired straight up at the maximum speed a gunpowder blast can accelerate it to, will never leave the lowest layer of Earth's atmosphere. A combination of gravity and air resistance will slow it down until it reaches a maximum height, whereupon it will fall back down to Earth's surface.
