How can we save Earth from the sun's searing death throes?
The article concludes with -"Astronomers estimate that there are somewhere between 0.25 and 10,000 rogue planets for every star, all drifting through the interstellar wastes of the Milky Way. That number is understandably broad, because we have precious few observations of rogue planets, and so it's difficult to construct solid statistics. But let's hope that our future descendants don't inadvertently add one more to the list.
Reference paper, A rich population of free-floating planets in the Upper Scorpius young stellar association, https://www.nature.com/articles/s41550-021-01513-x, 22-Dec-2021."Abstract The nature and origin of free-floating planets are still largely unconstrained because of a lack of large homogeneous samples to enable a statistical analysis of their properties.
My note. All the possible rogue planets reported are dated very young in the area near the Sun studied , perhaps 10 million years old or less. One possible formation mechanism identified is ejection from other planetary systems that formed . This seems to require much catastrophism and violence during protoplanetary disk evolution events postulated to explain the origin of planets.
