Original: Dividing the mass of 433 Eros by its density gives a volume of 3000 km3 , while the estimated 5 km radius of the ( assumed spherical ) Chicxulub Crater impactor yields a volume of only about 520 km3 .
Simplified: It is thought to be bigger than the impactor that created Chicxulub Crater in the Yucatán , which has been linked to the extinction of the dinosaurs .
