POSTPONED 1 DAY! Beyond Pluto: The Hunt for a Massive Planet X

Scott S. Sheppard

Thursday, February 21, 2019 - 18:30
Capital Science Evening Lecture
Scott Sheppard

THE SCHEDULED PROGRAM HAS BEEN POSTPONED 1 DAY.

It will take place Thursday, February 21, 2019, at 6:30 p.m.

Over the past few years, Dr. Sheppard and his team have been performing the largest and deepest survey ever attempted of our Solar System's fringes. In December 2018, he announced the most-distant object ever observed in our Solar System. His team's work has shown that the farthest-out-there objects—beyond the Kuiper Belt and the influence of the known major planets—are strangely grouped together in space. This suggests the existence of a yet-unobserved planet, sometimes called Planet X or Planet 9, more massive than the Earth, which is shaping the current orbits of these objects. Dr. Sheppard will discuss the most-recent discoveries at the edges of our Solar System.

This lecture will take place in the Carnegie Institution for Science headquarters, located at 1530 P Street Northwest, Washington, DC 20005. The lecture will also be streamed live. Attendance to the event is free, but registration is needed.
