I understand that the Poynting–Robertson effect describes solar radiation induced drag on certain sized dust particles causes them to lose orbital angular momentum and eventually fall into the Sun.

But how much mass per year is actually added to the Sun from effect?

    $\begingroup$ As a cheap estimate, compare the sun's surface area to the earth's surface area and multiply the terran estimate by that ratio. $\endgroup$ May 6 at 11:25
