Asteroid Close Encounter Today

Tumbling through space like a fumbled football, a peanut-shaped asteroid named 4179 Toutatis is expected to pass within a million miles (1.6 million kilometers) of Earth today.

“The September 29” approach is the closest in this century of any known asteroid at least as big as Toutatis,” said Steven Ostro, who studies asteroids at NASA’s Jet Propulsion Laboratory in Pasadena, California.
