Subject: Over time, are the masses of the earth and sun changing?

My thought is that the mass of the earth is increasing while the mass of 
the sun is decreasing. The earth's mass is increasing because it is 
constantly bombarded with stuff from space. On the other hand, the sun is 
radiating energy from its hydrogen fusion reactions. The fusion of four 
hydrogen atoms result in the creation of a slightly lower mass helium 
atom; therefore, the mass of the sun is decreasing? But wait! As for 
earth, stuff from space falls into the sun. So, if it is true that the 
sun's mass decreases due to fusion, and that the sun's mass increases due 
to imported solar debris, what is the net effect?
