Escape velocity is the minimum velocity required in order to project any body out of the gravitational field of a body mostly (planets) or any celestial body !
Kinetic energy = binding energy of the earth
1/2mv^2 = GMm/r
v^2 = 2GM/r
Taking square root on both the sides
V= √2GM/R
where G is the gravitational constant
M is the mass of the body
R is the radius of the body from its center of mass
