Astronomers have now discovered more than 5,000 planets orbiting other star systems. These planets are called “exoplanets,” and one of the tools that helps in searching for planets outside our solar system is the TESS satellite (Transiting Exoplanet Survey Satellite – TESS).
Recently, a group of astronomers used the TESS satellite to track and search for exoplanets. Revealing the discovery of an extrasolar planet. What is strange is that this planet floats freely. Without being affected by the gravity of the star, it is the first wandering planet discovered by the TESS satellite. Using the phenomenon of gravitational lensing (gravitational lensing) is the period during which a planet orbits in front of its star. This causes distortion of the light and reveals the presence of planets. This wandering planet has been named TIC 107150013.
The origins of these wandering stars are much debated in the astronomy community. But the widely held theory is that they are expelled from the host star system during its formation. Or perhaps it happened later due to gravitational interaction. Furthermore, simulations performed by astronomers indicate that free planets are likely to be abundant in our Milky Way Galaxy. But many of them have not been discovered.
