Even the Planetary Society is puzzled by this.
An extrasolar planet has been found in a system with 3 stars. Yes, three stars!
HD188753, the primary sun in the system, is located in the constellation Cygnus. It is also the closest to us at 149 light years away.
(At Warp 9, that would be a 17-hour trip. Earth hours' that is.)
The planet's orbit is only ~5m miles from HD188753, while the other two stars are locked in a binary orbit of each other, and that binary orbit in turn orbits HD188753 (the main star in the system), at a Saturn-like distance.
Guys, this is a huge find! And a head-scratcher for astronomers.
