Massive exoplanet with a very long orbit was discovered


It has the more mass than three Jupiter-size planets put together. Orbiting, it’s covering the distance of the entire outer solar system. Scientists named it HR 5183 b. “It’s very eccentric—it’s almost in a comet-like orbit. In our solar system, comets tend to have pretty eccentric orbits, but planets tend to be very circular, with very low eccentricity,” says Sarah Blunt, a Caltech NSF graduate fellow and coauthor of a study about. “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,” added Sarah Blunt.

The Lick Observatory in Northern California, the W. M. Keck Observatory in Hawaii and the McDonald Observatory in Texas all provided data for the study. Experts believe that the planet’s strange orbit is likely because it nudged another similar-size planet out of the solar system. „This newfound planet is another example of a system that is not the image of our Solar System but has remarkable features that make our universe incredibly rich in its diversity,” a report published by the California Institute of Technology (Caltech) concluded.
