1. A rogue planet does not orbit a star. Unlike Earth or Mars, a rogue planet moves freely through space without being gravitationally bound to a central star. Photo: Pinterest.

2. They may have once been planets in a star system. Many scientists believe that rogue planets may have originally formed in a star system but were later "kicked" out by gravitational collisions with other planets or their parent star. Photo: Pinterest.

3. There could be a huge number of them in the universe. Astronomers estimate that the number of rogue planets in the Milky Way could be many times the number of stars – meaning hundreds of billions of lonely planets floating in the dark. Photo: Pinterest.

4. Detecting them is extremely difficult. Because they do not emit light and do not reflect light from their star, wandering planets are very difficult to observe using traditional methods. Scientists often have to rely on the phenomenon of gravitational microlensing to detect them. Photo: Pinterest.

5. Some may be larger than Jupiter. Some of the rogue planets discovered are so large, even larger than Jupiter – the largest planet in the Solar System – that they are sometimes mistaken for brown dwarfs. Photo: Pinterest.

6. They may carry satellites. Despite having no parent star, some rogue planets may have their own satellites – like the Moon orbiting Earth – and may even retain a thin atmosphere. Photo: Pinterest.

7. Some could sustain life. Despite not receiving sunlight, some rogue planets could generate heat from their cores or through a powerful greenhouse effect, potentially creating conditions for life to exist in underground oceans or deep atmospheres. Photo: Pinterest.

8. They are a fascinating subject in science fiction. Wandering planets are often explored in science fiction films and stories as mysterious hideouts, alien bases, or the starting point of another civilization. Photo: Pinterest.
