A pair of 35-million-year-old craters on Earth thought to have been carved by comets now appears to be the result of a broken asteroid that generated a slowly delivered shower of debris over millions of years.

One crater is in Chesapeake Bay off the Maryland coast. The other, called the Popigai crater, is in north-central Siberia. Estimates of their age suggest they were created a mere 10,000 years apart.

Nothing new, forces caused by strong enough gravity can break asteroids to pieces same way comets. (like Shoemaker-Levy 9)

There are also double craters like Clearwater lakes in Canada
