Yes, rogue planet is not only possible but there are billions of rogue planets in our own galaxy milky way.
But, what kinds of planets are called rogue planets.
- Rogue planets are orphan planets. Some how they are not part of any solar system.
- Or they have been ejected from the planetary system in which they formed.
- They are also called wandering planets, starless planets, nomad planets.
- These planets don’t circle stars but they circle celestial bodies as small as planets
A dwarf named OTS 44 which is 15 times the mass of Jupitar is known to have a dusty disk of planet building material revolving around.
A brown dwarf also known as a failed star is of the size of planets and some rogue planets orbit these dwarfs
OTS 44 is located at 500 light years away in the Chamaeleon constellation.
