Yes if a matter which has a larger mass atracts the earth, the normal orbit would lose track because earth will be atracted to another object which has greater attraction than the sun

If the Sun and Earth were the only things in the solar system, ourplanet's orbit would be an ellipse of virtually constant shape and orientation in space. However, because the other planets pull on Earth, our orbit does change slightly over time, in orientation and in shape. Same for the other planetsorbits.
