William Cherry from Maple Ridge, B.C. asks "The Sun has been burning and depleting its hydrogen for billions of years.  Does this reduced mass have any effect on the orbit of the Earth around it?"  

Kaja Rotermund, a graduate student from the Physics Department at Dalhousie University says yes, but the effect is immeasurable because even though the sun's mass changing, it's negligible.
