$*$ Takes a Vector$3$D objects representing a celestial body

$*$ that you would reposition to$.$ However, it first ensures that the

$*$ destination between the current position and the celestial body is less than

$*$ the given threshold, otherwise it keeps refuel the the current position before repositioning.

$*$ @param destination : is the vector representing the position of a celestial body to which we are moving.

$*$ @param threshold :the distance between the current position and the destination must be less

$*$ than this threshold to enable us to reposition.

$*$ @param refuelAmount : is the amount by which the components of the vector is increased in order to decrease the distance between the current position and the destination.
