$15; buy tickets With Timothy Spahr, PhD, director of the Minor
Planet Center Our planet’s history is one of near misses and
direct hits. Past scars tell of many devastating impacts, some
of which nearly snuffed out life on Earth. How much of a threat
does an asteroid impact pose today? Join Timothy Spahr, PhD, as
he examines impact events of the past and looks at the close
encounters Earth’s future may hold. As director of the Minor
Planet Center, he collects and analyzes data from an average of
1,000 new asteroids per day, notifying NASA headquarters when an
object’s orbit will bring it close to Earth. Also in This Series
