Exploring the Planet Nine Hypothesis

Konstantin Batygin discusses the origins and development of the Planet Nine hypothesis, which began in 2014-2015. Inspired by the work of Chad Trujillo and Scott Sheppard, Batygin and Mike Brown investigated unusual orbital clustering in the Kuiper belt. Their analysis suggested a distant gravitational source, leading to the Planet Nine hypothesis. Since their 2016 paper, further research has refined their understanding, suggesting a smaller, closer planet than initially thought. Despite challenges, Batygin is optimistic about discovering Planet Nine within the next decade.
