How does earth affect the solar system?

Hint :The system is that the gravitationally bound system of the Sun and therefore the objects that orbit it, either directly or indirectly. Of the objects that orbit the Sun directly, the most important are the eight planets, with the rest being smaller objects, the dwarf planets and little system bodies.

Complete Step By Step Answer:
Our Earth is merely a little planet, but anything we now call a "planet" finishes up having a profound effect on the system. See the reason below. The foremost controversial phrase altogether of science, because it led to Pluto being rendered "not a planet". But the implications of clearing the neighborhood are actually seen across the orbit of the earth, an impact extending far beyond the immediate region round the planet itself.
Clearing the neighborhood means the region round the entire orbit of a planet is cleared of smaller bodies that would hit the earth; what smaller bodies remain are either controlled and trapped by the combined action of the planet and therefore the Sun, or trapped directly as moons.
In the case of the world, several asteroids are known where the asteroid is held as a companion of Earth in orbit, but never in position to hit us. The world acting alongside the Sun has them on top of things. One such asteroid is 3753 Cruithne.

Note :
Earth is actually among the "elite" bodies under the Sun, being one among only eight "planets capable of doing this over a variety of billions of kilometers. Astronomers had good reason to differentiate neighborhood-clearing bodies from other round worlds once they defined "planets" in 2006.
