New Evidence for Planet 9! SciShow News

The video discusses the ongoing search for Planet 9, a proposed super Earth beyond Neptune. Recent discoveries of distant objects like 2015 TG387 suggest the presence of this elusive planet. Simulations indicate that Planet 9 could influence the orbits of these objects. However, long-term space travel poses health risks due to cosmic radiation, which can damage the GI tract and other tissues. Despite these challenges, the pursuit of space exploration continues, with hopes of future missions to Mars and beyond.
