Trillions of planets, not stars

I think the article has a mistake: there are ~2000 planets for each star (not orbiting, obviously, unbound planets), and this implies trillions (~10^12) of planets, not stars, assuming the galaxy contains billions (~10^9) of stars. The Milky Way is usually assumed to contain between 100 & 400 billion stars.
