On Feb. 15, DA14, an asteroid the size of a football field, came within about 17,000 miles of Earth’s surface, skirting the orbits of communications satellites circling our planet. That same day, a meteor exploded in the skies above Russia with the force of a nuclear bomb.
While shattered glass from buildings injured 1,000 people, the Russians are relieved that the meteor detonated before hitting the Earth.
In his new book “Ark: Asteroid Impact,” Thomas A. Cahill describes what could happen if an asteroid much larger than that of DA14 were to strike the Earth, and how people might survive such a calamity. Cahill will talk about his book at 7:30 p.m. Saturday at The Avid Reader, 617 Second St. in downtown Davis.
