That is precisely what is so interesting.
Even a star wouldn't be anything more than a fat pixel, and the planet would be more like a thin pixel. Plus the star dimming, given the orbit would also be a long drawn phenomenon, like in case of earth(1 year).
I understand we ideally decide these things based on color of the light we see. And light waves stretch as the distance increases, and it can all be figured out by doppler effect.
But its still kind of mind blowing how much we can infer from just these things.
