how far are they from our solar system?
linked article say: "Since the seven planets orbit the star-- which is roughly 40 light years away-- fairly close to each other, ..."
Is this (40 ly) the distance from our system or what? If it's that's close, it's a bit of a wonder why they weren't found sooner. but then again, i ain't no astronomer.

actually, i'm talking about closeness for observation.

and anyway, 40 light years, means 40 years travelling at light speed, right? so once we get that tech (pre star-trek or star-wars tech, don't really care), it will take 40 years to reach. though probably not in my life time will this happen.
