Gravity, how fast a rocket must fly to escape the Earth?

Gravity (gravity) helps us to live on Earth, but it also makes it difficult to leave Earth.

Satellites override gravity by moving fast enough to continuously free fall around the Earth, as is the case with the ISS International Space Station, with velocities usually greater than 28,000 km / h.

But if you want to leave Earth, you need to move faster. This velocity is called escape velocity.

It takes a lot of fuel to achieve this speed, which is why early rockets, like Saturn V in the Apollo Moon exploration program, were so big: Because they had to carry enough fuel to fly to Moon. Compared to Saturn V, SpaceX's missiles are slightly smaller, but they even have to fly farther, because they have to carry people around the Moon and back.

Satellites repress gravity by moving fast enough to continuously free fall around the Earth.

SpaceX CEO Elon Musk must have been able to breathe a sigh of relief because he could launch missiles on Earth, instead of Jupiter. Because other planets in the Solar System have different gravity intensities, they also have different escape velocities.

On Jupiter, you must reach an incredible speed of nearly 220,000 km / h to escape it, because the planet has twice the mass of all other planets combined. You must achieve this speed if you want to launch missiles into space without being pulled back.

This is the escape velocity on each planet in the Solar System:
