Exoplanets and the search for life, sentence 1

They are far too faint to see beside their bright stars, so we catch them by tricks: when a planet passes in front of its star, the star dims a tiny bit.

Who acts: thousands, we, planet, star · What happens: be, see, catch, pass, dim · To what, where: bright stars, thousands, front, tiny bit
