"HR 5183, also known as HD 120066, is a G0-type star approximately 103 light-years away.
Named HR 5183b, the newly-discovered planet is roughly 3.2 times the mass of Jupiter.
“This planet is unlike the planets in our Solar System, but more than that, it is unlike any other exoplanets we have discovered so far,” said Caltech graduate student Sarah Blunt. “We detected this slingshot motion. We saw the planet come in and now it’s on its way out. That creates such a distinctive signature that we can be sure that this is a real planet, even though we haven’t seen a complete orbit.”
For HR 5183b to be on such an eccentric orbit, it must have gotten a gravitational kick from some other object.
The most plausible scenario is that the planet once had a neighbor of similar size. When the two planets got close enough to each other, one pushed the other out of the planetary system, forcing HR 5183b into a highly eccentric orbit."

--Actually, the Most Plausible Scenario would be that this odd Planet was DESIGNED to do just what it's doing....and why & what for?.....who knows but the Designer of it....these astronomers don't know....that's why they are hypothesizing "scenarios".
