Heavenly Bodies


Our solar system has dozens of what are called Binary Minor Planets, which are actually asteroids and comets. Derek Richardson, an astronomy prof at the University of Maryland, will discuss the heavenly bodies at a fact- and trivia-filled lecture tonight. "Since 1999, we've found 60 of them," he says. "We've got binaries popping up everywhere."
Thu., March 16, 8 p.m.
