Part 5/9:
These observations suggest that for every star in the galaxy, there could be nearly two Jupiter-mass rogue planets. Moreover, some studies estimate that rogue planets could outnumber stars by up to 100,000 to one, although these figures are based on different models and methods.
Key Characteristics
Mass and Composition: The detected floating planets have masses akin to Earth or Jupiter, but their precise composition remains uncertain. They are believed to be cold, dark worlds drifting through space.
Origin: Many of these rogue planets likely formed around stars but were ejected due to gravitational interactions. Others might have formed in isolation—what scientists call "failed stars"—lacking the mass to ignite nuclear fusion.
