Researchers have found two planets in a solar system 5,000 light-years away that appears to be structured in some important ways like our own.
The planets are gas giants similar to but smaller than Jupiter and Saturn, and their relative sizes are also similar. In addition, they circle their star at a distance proportional to the distances of Jupiter and Saturn from the sun.
"This is the first time we've found a Jupiter-like planet in the same system as a Saturn planet," said Scott Gaudi of Ohio State University, lead investigator on the project. "There's reason now to believe there are probably many more solar systems like it."
The discovery, published today in the online edition of the journal Science, lends support to the long-held belief of many astronomers that there are many planets orbiting their stars in ways similar to our solar system. Most of the more than 260 planets discovered so far have orbited their suns far more closely than theorized, and the planets have been larger than expected. more...
