Montauk Observatory Lecture: The Search for the Ninth Planet at John Jermain Memorial Library

May 10, 2018 @ 7:00 pm - 9:00 pm

Free

LECTURE & OBSERVING
Thursday, May 10, 2018, 7:00 PM. “The Search for the Ninth Planet.”
Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus, Neptune…these 
are the 8 official planets of the solar system. Distant Pluto, once 
considered the 9th planet, was relegated to a new category: 
“Trans-Neptunian Objects” or TNOs. Many other TNOs similar to Pluto 
(such as Eris, Makemake, Sedna, and Quaoar) were discovered brimming on 
the edge on the known solar system. As the number of TNOs grew, 
astronomers made a curious discovery: most of their orbits were 
clustered in ways that seemed difficult to ascribe to pure chance. Could 
their odd behavior be the result of an unseen but massive new planet, to 
Planet Nine?

NASA Solar System Ambassador, William Francis Taylor, will discuss the 
search for Planet Nine and planetary discovery. Weather permitting, he 
will also set up a telescope after the lecture and show you around the 
night sky.

This event will beheld at the John Jermain Memorial Library, 201 Main 
Street, Sag Harbor NY 11963. To register, call the library at 631-725-0049.

This event is free, although tax-deductible donations (made through our 
website) to help support Montauk Observatory are greatly appreciated.
