"Scientists Uncover Ultra-Dense Exoplanet Defying Expectations"
Astronomers have discovered an exoplanet called TOI-1853b, which is roughly the size of Neptune but has a density denser than solid steel. Located 545 light-years away, the planet orbits a K2 dwarf star and has a radius 3.5 times that of Earth, carrying approximately 73 Earth masses. Scientists believe that the planet was originally water-rich and underwent multiple high-velocity collisions, stripping away lighter elements and leaving behind only dense rocky material. This discovery highlights the diverse and strange nature of planets in the universe.
