HR 5183 b slingshots around more like a comet - a long, elliptical orbit with the star at one end of the oval. If HR 5183 b were in our Solar System, it would swing in closer than the orbit of Jupiter, and then way out farther than the orbit of Neptune. HR 5183 b is a massive gas giant that orbits a Sun-like main sequence star called HR 5183 around 103 light-years away. Because the exoplanet's orbit is so weird - it takes around 74 years to orbit the star, swooping out as far as over 30 astronomical units...
