If two mass separated, it will affect their velocity. But does this hydrogen escapee like a rocket gas. Or it is just a restructure or a bit move of CoG. One also note if it not too fast escape as earth rotate the overall effect depend upon the uniformity of the “escape” as the net effect can be zero or more depends upon its location on earth. Mostly as it is not align with the tangent of travel, it will affect. How much as point out relates also the mass. But even the minor variations make the polar star changes. It will have affect.
