The planet orbits a star called Kappa Andromedae that is 2.5 times the mass of the sun and is located 170 light-years away from Earth. As a gas giant larger than Jupiter , it s classified as a super-Jupiter.
Astronomers say the object s immense size places it right on the edge of the classifications for giant planets and a type of failed star known as a brown dwarf. Its official name is Kappa Andromedae b, or Kappa And b for short, and it likely has a reddish glow, researchers said.
The super-Jupiter Kappa Andromedae b, shown here in an artist s rendering, circles its star at nearly twice the distance that Neptune orbits hotels chicago the sun. With a mass about 13 times Jupiter hotels chicago s, the object glows with a reddish color.

According to conventional models of planetary formation, Kappa And b falls just shy of be ing able to generate energy by fusion, at which point it would be considered a b rown dwarf rather than a planet, Michael McElwain, a member of the discovery hotels chicago team at s Goddard Space F light Center in Greenbelt, Md., said in a Nov.ಓ statement. But this isn t definitive, and other considera tions could nudge the object across hotels chicago the line into brown dwarf territor [ Super-Jupiter Disco very in Photos (Gallery) ]
The object is an interesting hotels chicago test case for theories o f planet formation, scientists say. Based on observations of this system, the su per Jupiter appears to have formed in the same way ordinary, lower-mass exoplane ts do, by coalescing from a protoplanetary disk of material orbiting a nascent star.
That s because its orbit, somewhat wider than the path Neptune takes around our sun, is at a comparable distance to planetary orbits in the solar system. Additionally, its star, Kappa Andromedae, is relatively hotels chicago young, at about 30 million years old (for comparison, the sun is roughly 5 billion years old). These clues point toward a formation story typical of smaller planets.
Previously, some scientists had doubted that such large sta rs could give birth to planets in protoplanetary disks. The new finding indicate s that this star probably did just that.
The new photo was snapped by Japan s Subaru 8-meter t elescope on the summit of Mauna Kea in Hawaii. hotels chicago Alien planets are extremely difficult to image directly because their stars ar e always so much brighter, and outshine any planets.
To capture this picture, as tronomers looked in infrared light, and used a technique to hide the glare from the star in order to reveal the relatively faint dot of light from the planet. hotels chicago M ore than 800 planets have been discovered beyond hotels chicago the solar system, but only a ha ndful have been imaged directly so far.
The parent star of Kappa And b, Kappa A ndromedae, can be seen by stargazers from Earth without requiring a telescope, N ASA officials said. The star can be easily seen in the night sky above the const ellation of Pegasus from suburban hotels chicago areas, they added.
