There are hundreds and thousands of planets out there in the solar system and we're barely just scratching the surface with each discovery. Now, scientists have discovered yet another planet and this time it looks like this could be the smallest free-floating planet ever detected.

This discovery was made by the University of Warsaw researchers in the middle of the Milky Way. From what we know so far, this new planet is said to be between the size of Earth and Mars. These kinds of free-floating planets are usually difficult to detect.

Rogue planets don't orbit stars, they are gravitationally unattached to any host star. They don't emit any visible radiation, so they cannot be detected using traditional astrophysical techniques. 1/5

For this discovery, the researchers used a technique called “microlensing". The technique allows scientists to find planets they wouldn't be able to. Przemek Mroz, one of the co-authors of the paper explained it and said, "Rogue planets don't orbit stars, they are gravitationally unattached to any host star. They don't emit any visible radiation, so they cannot be detected using traditional astrophysical techniques."
