This is one of those things that seems incredible at first, but when you think about it, isn't actually that strange at all: Yes, some of these planets are massive, but the problem has always been (in observing or visiting them) their vast distance from Earth, not their actual sizes.
what makes it incredible is not the fact itself but the visualization and the realization of it.
i wasn't aware of the fact, and even though after thinking about it it's kind of obvious, the visualization really helps to let the fact sink in and make it memorable.
