The crater is said to have been formed by a 3km (1.8mi) diameter asteroid, and caused a crater at least 70km (43.8mi) in diameter.

In 2006, a group of scientists drilling into the site discovered a 25cm (9.8in) diameter fragment of the original asteroid, at a depth of about 770m (842yards) below the surface.

As drilling on large impact structures had never produced such fragments, and it had previously been believed that all large asteroids vaporized almost entirely on impact.
