OGLE-2016-BLG-1928 is an exoplanet located in the constellation Sagittarius, discovered via gravitational microlensing. It is likely to be a rogue (free-floating) planet, as no host star was detected within 8 astronomical units.
This likely free-floating planet has a mass of either 0.3 M🜨, if it is located within the galactic disk, or 2 M🜨 if it is located in the galactic bulge. The former scenario is the most likely. Low-mass rogue planets like OGLE-2016-BLG-1928 are thought to be very common in the Milky Way, but few have been spotted as they are very hard to detect. It is believed that these planets have been ejected from their origin planetary systems.
