The orbits of the individual asteroid-like bodies within the Kuiper belt trace out highly elongated elliptical paths, requiring\u0026nbsp;hundreds to thousands of years to complete a single revolution around the sun.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EAlthough the majority of the Kuiper belt\u0026rsquo;s dynamical\u0026nbsp;structure can be understood within the framework of the known eight-planet solar system, bodies with orbital periods longer than about 4,000 years exhibit a peculiar orbital alignment that eludes explanation. What sculpts this alignment and how is it preserved?\u003C\/p\u003E\r\n\r\n\u003Cp\u003EIn this talk, I will argue that the observed clustering of Kuiper belt orbits can be maintained by a distant, eccentric, Neptune-like planet, whose orbit lies in approximately the same plane as those of the distant Kuiper belt objects, but is anti-aligned with respect to those of the small bodies. In addition to accounting for the observed grouping of orbits, the existence of such a planet naturally explains other, seemingly unrelated dynamical features of the solar system.\u003C\/p\u003E\r\n\r\n\u003Ch5\u003E\u003Cstrong\u003EAbout the Speaker\u003C\/strong\u003E\u003C\/h5\u003E\r\n\r\n\u003Cp\u003EForbes\u0026nbsp;named professor \u003Ca href=\u0022https:\/\/www.konstantinbatygin.com\/\u0022\u003EKonstantin Batygin\u003C\/a\u003E the \u0026ldquo;next physics rock star\u0026rdquo; in its 2015 list of \u0026ldquo;30 Under 30: Young Scientists Who Are Changing the World.\u0026rdquo; He received his bachelor\u0026rsquo;s degree in physics from University of California, Santa Cruz, in 2008, before pursuing graduate studies at California Institute of Technology.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EBatygin has authored over 70 scientific publications,, His\u0026nbsp;research has been featured on\u0026nbsp;Nature, as well as the front cover of Scientific American.\u003C\/p\u003E\r\n\r\n\u003Cp\u003EPrior to joining the faculty at California Institute of Technology in 2014, Batygin was a visiting scientist at Observatoire de la C\u0026ocirc;te d\u0026#39;Azur, in Nice, France, and an ITC postdoctoral fellow at Harvard University.
