The Solar System contains many small, unexplored worlds in a vast region of space beyond Neptune and Pluto. Recent discoveries include dwarf planets and smaller Kuiper Belt objects, and astronomers are searching for a new large planet that may orbit 700 times farther from the Sun than the Earth.

Join us on Facebook Live as geologist Ross Irwin from the Museum's Center for Earth and Planetary Studies talks about the solar system beyond Pluto. 

Planning to attend in-person? Meet in the Exploring the Planets gallery.


Every Wednesday at 12:30 p.m. we will go live on the National Air and Space Museum Facebook page with an Ask an Expert talk. We’ll select a different aviation or space topic each week, and a Museum staff member will discuss the history, stories, or personalities related to a specific artifact or exhibition in the Museum. Tune in on Facebook Live each week to join the talk and ask our experts questions.
