Some British, Australian and American astronomers believe they've stumbled upon a planetary system similar to ours.
It includes a Jupiter-like body circling a distant star, which raises the prospect of someday finding a planet resembling Earth.
Hugh Jones of Liverpool John Moores University said his team discovered the system.
Jones said the star is similar to the sun in structure and brightness and appears to be about the same age. The planet is traveling around the star in an orbital path similar in shape and distance to the one that Jupiter follows around our sun.
Nearly 110 planets orbiting stars other than the sun have been found within the past decade. But one British astronomer said none really resembled our solar system until now.
