Scientists announced today the discovery of a fifth planet in a distant star system that that now looks like a "cousin" to our own.
Known as 55 Cancri, the sun-like star harbors the most number of planets ever discovered outside our solar system.
"We now know that our sun and its family of planets is not unusual," study team member Geoffrey Marcy of the University of California, Berkeley told reporters in a teleconference. "Architecturally, this new planetary system is reminiscent of ours, albeit souped-up. All the planets in this new system are more massive by factors of 5 to 10."

Weit über 200 extrasolare Planeten wurden bislang um ferne Sonnen aufgespürt, doch der Stern 55 Cancri scheint etwas ganz Besonderes zu sein: Heute nämlich gaben amerikanische Astronomen die Entdeckung eines fünften Planeten um den Stern bekannt. Dieser befindet sich sogar in der habitablen Zone von 55 Cancri, in der flüssiges Wasser möglich ist. Nach weiteren Planeten des Systems wird gesucht.

Planetary System Detected Around SETI@home Target Star
SETI@home Update, November 8, 2007
by Amir Alexander
When first discovered over a decade ago they appeared as lonely giants, circling their home stars in splendid isolation amid the emptiness of interstellar space. Then, as more and more exoplanets were detected, some of them clustered together in groups of twos and threes orbiting the same star. And now, at last, a fully formed planetary system, with five different planets of varying sizes and orbits has been found, orbiting a star more than 40 light years away. Significantly, it is the very same star, 55 Cancri, that was one of the chief targets of the SETI@home reobservations at Arecibo in March 2003.

About 250 exoplanets have been discovered to date, and more are being announced at a steady rate. What began as a bizarre collection of hot Jupiters orbiting their stars at dizzying speeds soon became a more representative sample, including smaller, cooler, and more distant planets. Now whole planetary systems are emerging from the shadows, both similar and intriguingly different from the one we call home. But even, notes Marcy, is only one small step in our scientific quest. “Earth-like planets are the next destination."
