It has been suggested that Sedna\u2019s orbit was likely modified by a passing star early in the history of the solar system.  The Planet Nine hypothesis was born.

If the observations are trustworthy, it appears that Planet Nine &#8211; ten time as massive as the Earth &#8211; is probably real. Scientists are confident that within a few years an astronomer somewhere will  find a faint, slow-moving point of light in the night sky and  triumphantly announce the discovery of another new planet in our solar  system. <\/p>\n\n\n\n<p>Read more at : <a href=\"https:\/\/physicstoday.scitation.org\/doi\/10.1063\/PT.3.4172\" target=\"_blank\" rel=\"noreferrer noopener\" aria-label=\" (opens in a new tab)\">Physics Today<\/a> <\/p>\n","protected":false},"excerpt":{"rendered":"<p>Space Sciences Date: March 2019 Source: Physics Today In 2002 an object orbiting inside the solar system, now known as Sedna, was uncovered (see Physics Today, June 2004, page 23).
