Benjamin Dean Astronomy Lecture
Tiny Moons around Asteroids
Monday, April 4 | 7:30 pm
Morrison Planetarium
​Dr. Franck Marchis, SETI Institute

​After decades of speculation, the existence of multiple asteroids—asteroids with one or several companions around them—has been observationally confirmed. Today more than 200 companions of asteroids are known, and half of them were discovered by large worldwide network of professional and amateur astronomers equipped with small and medium size telescopes. Dr. Marchis will briefly describe the technology used today that make it possible to image several multiple asteroid systems and present several NASA and ESA space mission concepts dedicated to explore these new worlds in-situ. $8 members, $10-12 non-members.
