In a rare direct image of a world past Earth, astronomers have marked a planet 13 times more huge than Jupiter, the largest main planet in our own solar system. The planet orbits a star called Kappa Andromeda that is 2.5 times the mass of the sun and is placed 170 light-years gone from Earth. As a gas huge better than Jupiter, it's top secret as a "super-Jupiter."
Astronomers declare the object's immense size spaces it right on the border of the classifications for giant planets and a type of unsuccessful star known as a brown dwarf. Michael McElwain, one of a member of the detection team at NASA's Goddard Space Flight Center in Greenbelt, Md., said in a Nov. 19 report. "But this isn't ultimate, and other considerations could push the object across the line into tan dwarf territory.
