The asteroid is estimated to be 15 kilometers across (about 8 miles) and travelling about 20 kilometers per second ( alittle more than 10 mils per second) The center of the impact crater is off shore of the Yucatan Peninsula in the Gulf of Mexico. The crater ring is about 200 km across and the part on shore is still visible.
