PENDLETON — The year 2013 has been an eventful time for asteroids and comets. Are these celestial objects on a collision course with Earth?
An undiscovered asteroid 65 feet in diameter entered the Earth’s atmosphere over central Russia at a speed in excess of Mach 50 and exploded with a force equal to 40 Hiroshima nuclear bombs.
You only need to look at the mile-wide meteor crater in Arizona to understand the utter devastation even a small asteroid can do. There have been times in Earth’s history when asteroids have collided with us, causing mass extinction events.
Greg McCauley, executive director of the Link Observatory in Martinsville, will be at the Pendleton Community Library, 595 E. Water St., Pendleton, for a fascinating look at asteroids, comets and near-earth objects on Saturday at 2 p.m.
The program is free and open to the public. It is appropriate for all ages. Reservations are appreciated. Call the library at 778-7527 or email firstname.lastname@example.org to register.
