Giant Exoplanet Has Extreme Orbit

A newly discovered exoplanet, three times the size of Jupiter, has been found to have a bizarre orbit around its star. The massive gas giant, known as HR 5183 b, takes 45 to 100 years to complete its orbit, which is highly eccentric, swerving in close to its sun and then whip-lashing out to the farther reaches of its solar system. Scientists speculate that another body or planet interacted with HR 5183 b at some time in the past and deflected its natural course. "Our universe is full of lots of weird solar systems totally unlike our own," Sarah Blunt, a graduate student at Caltech commented to NBC News.

The above video depiction compares the eccentric orbit of HR 5183 b to the more circular orbits of the planets in our own solar system.
