Newly Discovered Exoplanet Shocks Scientists | Exoplanets (New)

Recently, Astronomers have discovered a strange exoplanet whose bizarre orbit makes it unlike anything they have ever seen.
Known as HR 5183b, this Exoplanet is at least three times more massive than Jupiter, taking a long, wild orbit around a sun-like star, HR 5183, which lies about 100 light years away from Earth.
Because of the exoplanet's odd orbit - HR 5183 B takes around 74 years to orbit its parent star, swooping out as far as over 30 AU(4,500,000,000 Km; 2,790,000,000 Miles), While its closest approach to its parent star is less than 5 AU (750,000,000 Km; 465,000,000 Miles).
How was HR 5183 b discovered?
The star system was under long-term surveillance as part of an exoplanet search using the radial velocity method. The radial velocity method is one of the most reliable methods for finding exoplanets, based on the very slight movement of the star as it is tugged out of place by the gravity of its orbiting bodies.
But how did this exoplanet get into such a strange orbit?
The most likely scenario was that HR 5183 b was once neighbored by another planet of similar size. When they got close enough to each other, the gravitational interaction could have kicked HR 5183 b into its orbit - and kicked the other planet out of the star system entirely.
This Newfound planet proves to us that our universe is far more interesting than we thought it would be.
