Just a little bit. Right now you exert a force equal in magnitude and opposite in direction to the earth. The earth just has more mass and,
therefore, more inertia, so you barely move it.
Force of gravity = (GMm)/(r^2)
Where:
G = gravitational constant
M = mass of object one (earth)
m = mass of object two (you)
r = distance between object one and two.
The force on object one by object two is the same exact magnitude as the force on object two by object one.
The reason you hardly move the earth, while the earth moves you a lot, even though you both exert the same force.
F = ma
Where:
F = Force (of gravity in this case)
m = mass of object the force is acting on
a = acceleration of the object
Deriving this:
a = F/m
Therefore, as the mass increases, and the force of gravity remains constant, the resulting acceleration (as you would accelerate toward the earth)
decreases.
