There’s been a puzzling amount of writing about how this planetary system is so much different from the extrasolar planetary systems detected so far — that’s clearly because the only detectable ones are the ones that look weird compared with ours.

I would love an astronomer to figure out how far away our solar system could be detected using our best equipment. The first planet detected would be Jupiter, but would its 12 year revolution period be too slow to provide a Doppler shift to the sun’s light?
