Comets! Comets! Comets! Have you ever made a comet? Come to the Family
Night at Yerkes Observatory and make a very cold fizzing comet model! Learn
about how comets orbit the Sun and how their sand grain size debris creates
meteors (shooting stars). We will observe the starry sky if the weather is
clear, so please dress warmly.
