The extrasolar planets, or exoplanets , that swirl around the star TOI-201 have orbits that are changing so rapidly that astronomers can see the changes in real time. The behavior of the system, located around 370 light-years from Earth, is something scientists have never seen before. "Most planetary systems appear as 'peas in a pod,' meaning the planets have a similar range of parameters and share a similar orbital plane," team member Amaury Triaud, from the University of Birmingham in the U.K., said in a statement.…
