You know the science of planet hunting is getting mainstream when there's very little fanfare for the discovery of 3 new extrasolar planets with the size of Jupiter. ...

I know how you feel. The interesting thing for me is that they were discovered using local (South African) telescopes.
You would expect our (South African) media to all over this, but finding new Jupiter sized planets is so common it doesn't even register to people anymore.


Back on OP:
Two day orbit for a Jupiter size planet, thats incredibly fast, in the linked document the distance between the star and the planet/s is not mentioned.
Do you perhaps know it? I presume you wrote the story.

I don't think this method can find ALL the planets. I'd say we can only find a tiny fraction of the planets that orbit in the same or similar plane with Earth, right? I really hate it when data (or energy or anything) has such a low "efficiency".

Of course. But it is one of the easiest planet-detection methods.

it's still cool we are finding new planets. I suspect that will happen as long as we continue to look.



By the way, how many have we (humans) discovered up to now? It should be approaching 200 soon.
