Astronomers have just discovered a planet with an 'unlike anyone' orbit, moving around the central star like a comet instead of like other planets.
HR 5183 b is a gas giant with 3 times the mass of Jupiter, orbiting a sun-like star called HR 5183 103 light-years from Earth.
It does not have the elliptical orbit common in most planets. Instead, HR 5183 b moves in a long elliptical orbit , with the central star on the opposite side of the oval, according to arXiv.

This is the first time Earth scientists have found a planet with such an orbit. If HR 5183 b was a member of the Solar System, it would be closer to the Sun than Jupiter and retreat farther than Neptune.
Because the 'style' moved so bizarre, HR 5183 b took about 74 years to complete the orbit around the central star, traveling the equivalent of 30 astronomical units, according to research author Sarah Blunt of Harvard University (USA).
It can be said that astronomers were extremely lucky to be able to discover this special planet.
Comets can change spherical orbits as they approach larger objects in the solar system, and researchers think the same thing is happening to HR 5183-b.
It can come close to another planet of similar size and when the two planets get close enough, the gravitational interaction can push HR 5183-b into an unusual orbit.
