Hello, Marino!

An individual graviton does not have any gravity.  It is a massless
particle that conducts gravity.  Even the word "particle" is a little
misleading.  The correct term to describe gravitons is boson.  A boson has
an energy force, but no mass.  Photons are another example of bosons.

Since a graviton has no mass, it has no gravity.  It simply carries the
force of gravity between objects with mass.

Like other bosons, gravitons probably behave somewhat like waves and
somewhat like packets of energy.  This is why the term "particle" is
misleading.  I like to think of gravitons as invisible ropes that tie two
objects together.  If you've ever taken a rope, laid it out straight, then
whipped it, you know that the distance between the two ends of the rope
shrinks as the waves in the rope get larger.  The more energy you use to
whip the rope, the bigger the waves in it, and the two ends of the rope
move closer together.

Think of gravity as the force that whips the rope.  The closer two objects
are together, the more gravitational force they have on each other.  This
makes the waves in the rope bigger, and the two objects are pulled together
by the rope.

The ropes, or gravitons, don't have any gravitational pull themselves.
They are just the carrier of the gravity force.
