SOLAR SYSTEM

Detailed explanation-1: -The amount of velocity needed to escape our planets gravity is approx 11km per second, which is known as escape velocity.

Detailed explanation-2: -Escape velocity is not necessary to leave the earth, unless the object has no thrust or other means of propulsion.

Detailed explanation-3: -Space Environment Since escape velocity depends on the mass of the planet or moon that a spacecraft is blasting off of, a spacecraft leaving the moon’s surface could go slower than one blasting off of the Earth, because the moon has less gravity than the Earth.

Detailed explanation-4: -In physics, escape velocity is the minimum speed needed for an object to escape from the gravitational influence of a massive body. Escape velocity (ve) = (2GM/R)1/2. Its Value is 11.2km/s for earth and 2.4km/s for moon.
