javawithjiva, The sun makes up 99.9% of all the matter in the solar system, and Jupiter makes up about 70% of the remaining 0.1%.
So if an alien spaceship visited our solar system, said, "Nah, there's nothing here apart from the Sun and that gas planet," and left again, they would be 99.97% correct regarding mass.
Earth is basically indistinguishable from a rounding error.
