Missing Planet... a dead star?
Did a dying star give birth to several solar systems with similar elements like ours before finally dying? Is Proxima Centuri also the product of the same star that gave birth to our system? Because the star is presumed dead where is it ? Is this planet a the dead star that gave birth to us? Some have called this Planet X or Planet 9. Further work since 2014 showed that this massive ninth planet likely exists by further constraining its possible properties. Analysis of "neighboring" small body orbits suggest that it is several times more massive than Earth, possibly as much as 15 times more so, and at the closest point of its extremely stretched, oblong orbit it is at least 200 times farther away from the Sun than Earth. (This is over 5 times more distant than Pluto.) The general prevailing theory is that our solar system formed billions of years ago near a supernova. But the new scenario instead begins with a giant type of star called a Wolf-Ray...
