How to negate gravitational influence of specific objects in space?

The way the Earth travels is dependent on the gravitational influence of matter that surrounds it. This question is of how/if we can prevent or reduce certain objects effects on Earths movements through gravitational pull or attraction.

Clarifications:

• Earth was an example. This is more about the premise not the object.
• Modern science or accepted theories are preferred but fictional ideas are also welcome if they aren't radically unrealistic.
• I am asking about potential ways to negate the gravitational attraction of specific objects on specific celestial bodies.

Bonus Question: If it isn't possible now, could it be accomplished in the future
