Astronomers have discovered a floating planet in the Milky Way that is slightly smaller than the Earth and that orbits around each star.
Scientists say this is the smallest useless planet found so far.
In 2011, the team discovered 10 celestial bodies the size of Jupiter that did not have a mother star in the 10 astronomical units. An AE is the distance between the earth and the sun.
While the most famous planets orbit around one star, researchers believe that there may be many malignant planets in the galaxy, perhaps even more than the number of stars in the Milky Way.
Scientists used an astronomical phenomenon known as gravitational micro-licensing to discover a planet that has proven itself by diverting light from distant stars.
The result is an effect similar to a gigantic magnifying glass that illuminates the light of the original star in the background and reveals the presence of a massive object.
Gravity micro-licensing is only possible if the astronomer’s telescope is in an almost ideal position in relation to the observed object and the source star.
said Przemek Mroz, a graduate student at the California Institute of Technology and lead author of a study published in the journal Letters of Astrophysical : The chance of observing micro lenses is extremely small because the three objects – source, lens and observer – need to be almost perfectly aligned.
Researchers examined data collected during microscopy of the Galactic Arc, the central part of the Milky Way.

They used the 1.3 meter long Warsaw telescope at the Las Campanas Observatory in Chile to collect the data.
Researchers say that the newly discovered planet is the smallest rogue world ever discovered, and models suggest that it may have a mass somewhere between Earth and Mars.
said Radoslaw Polesski of the University of Warsaw Astronomical Observatory, who co-authored the study: When we first noticed this event, it was clear that it must have been caused by an extremely small object.
We can rule out a planet with a star within eight AUs.
Astronomers believe that floating planets may have formed in the rotating discs of dense gas and dust around the stars and were ejected from their mother planetary system after gravity interaction with other bodies.
It is said that the study of these objects could enable astronomers to learn more about the tumultuous past of planetary systems such as the solar system.
