What Are Orphan Planets? The Mysterious World Of Space, Where Some Planets Are Not Gravitationally Bound To Any Star

We all think that everything in this universe is completely arranged and disciplined, meaning like take our solar system as an example, there is a star in the middle and all the planets and objects are orbiting it. Here the whole game is of gravity and the stars keep rotating the planets around them. But can it ever be possible that a planet not to orbit a star or will be thrown out of the solar system forever? Do such planets really exist in the universe on which the gravity of a star has no right? So the answer is yes, and we commonly know these planets as orphan planets.

These are some such planets that have been ejected from the planetary system in which they formed and therefore wandering alone in Space. They are also called rogue or wandering planets. Many people think that the planets in the universe do not exist without their stars. But actually, it is not so. These free-floating objects do not revolve around a star but are like planets. There is no clear information about their origin so far, but it is likely that they may have been tied to a star in their early stage.

It should come as no surprise that the number of such "rogue" or "sunless" planets in the universe is far more than the total stars. According to scientists, there could be billions to trillions of rogue planets in the Milky Way alone. Scientists have so far discovered 170 such free-floating planets, which are wandering in space alone without gravitationally bound to any star. Because of wandering alone in the universe without their host star, these planets do not receive any kind of light, so they are surrounded by terrible darkness and cold.

The story of the formation of planets in the solar system is quite interesting. Sometimes new planets are formed from the dust and gas around the stars, and sometimes some planets are formed on their own. Rogue planets are also included in the list of self-forming planets. They are usually formed when some new planets are being formed in a solar system and many large objects keep colliding with each other. In this collision, the orbit of a planet changes, and due to deviating from the orbit, that planet gets ejected from its solar system. And even the gravity of its own star can't bring it back and it then keeps wandering forever in the infinite universe.
