All Things Space, UFOs, etc.New 5th planet found in system of remarkably diverse worlds Posted on August 13, 2025 by Administrator L 98-59 is a fascinating planetary system only 35 light-years from Earth. Astronomers previously found four small exoplanets orbiting the red dwarf star. And now a research team led by the Trottier Institute for Research on Exoplanets (IREx) at the University of Montreal in Canada has confirmed a fifth planet. The researchers said on July 22, 2025, that the planet – L 98-59 f – is orbiting in the star’s habitable zone, where water could potentially exist. In addition, the research team has determined the sizes and masses of all the planets with unprecedented precision.
