Slightly larger than the size of Jupiter, the largest in our solar system, the newly discovered exoplanet is orbiting a star 2,000 light years from Earth that has found its way into the Milky Way. The pair are believed to be part of the Helmi stream, a group of stars that remains after its mini-galaxy was devoured by the Milky Way some six to nine billion years ago, said the study in Science Express. http://news.yahoo.com/s/afp/20101118/sc_afp/usspaceastronomyeuropegermanychile

It's a very common phenomena observed in the majority of exoplanets discovered or in most star systems studied to have "hot Jupiters", often many times the size of Jupiter, on closer orbits than Mercury has with our star. Systems like ours are oddities which do not occur as often as "hot Jupiter" systems though still enough for our solar system to not be an entirely unique case in the universe precluding the possibility of terrestrial planets in the habitable zone in nearby systems.
