If we observed only one source star, we would have to wait almost a million year to see the source being microlensed." "Chances of observing microlensing are extremely slim because three objects-source, lens, and observer-must be nearly perfectly aligned. Przemek Mroz, a postdoctoral scholar at the California Institute of Technology and lead author said. "The observer will measure a short brightening of the source star," Dr. Replicating the gravity of the planet as a magnifying glass, light of a nearby bright star is then bent behind the planet so that astronomers can spot the planet. To find them, astronomers use gravitational microlensing. See, free-floating planets emit no radiation because they don't come with a parent star. They're usually discovered when observing light from their host stars. The first is that exoplanets are extremely tough to spot. The discovery is pretty historic for several reasons. How was it found? A rogue planet bends the light of a star nearby. The finding of this tiny planet has been documented in a new study by the same astronomers. All of these planets were found in the Milky Way galaxy. However, in recent years Polish astronomers discovered evidence of free-floating planets which are not attached gravitationally to any star. Scientists believe some even experience liquid iron rain. Many of these unique planets also have extremely different weather patterns. These planets often orbit around a star than a sun. To date, there are over 4,000 such rogue planets, which scientists have also called, exoplanets. It's smaller than Earth and has roughly a similar mass to Mars. It experiences neither day nor night and remains perpetually in darkness, wandering all by itself, devoid of contact with other gravitational siblings.Īccording to scientists, such a "rogue" planet is not the only one of its kind but it's the smallest found so far. Deep within the Milky Way galaxy, there's a tiny lone planet that is floating aimlessly by itself. ![]()
