The comet or asteroid which struck Earth has been calculated to have been 10 to 15 kilometres in diameter and initially created a crater 100 kilometres (62 miles) wide and 30 The Chicxulub crater isn’t visible on the surface because it is covered by younger, relatively undeformed sediments. It was identified from a nearly circular gravity anomaly along the northwestern edge of the Yucatán Peninsula (Figure 1). 2,3 There’s disagreement on the crater’s exact size, but its diameter is approximately 110 miles The ~180-km-diameter Chicxulub peak-ring crater and ~240-km multiring basin, produced by the impact that terminated the Cretaceous, is the largest remaining intact impact basin on Earth.

[3] One of the greatest scars on our planet is hidden beneath the Yucatán Peninsula and the Gulf of Mexico. The buried crater, over 90 miles in diameter, was created when a massive asteroid struck the Chicxulub crater is an impact crater buried underneath the Yucatán Peninsula in Mexico.

Chicxulub crater is an crater buried underneath Yucatan, Mexico. It had a diameter of 150 - 180 kilometers. It was formed by the impact of the asteroid that killed the Dinosaurs 65 millions of years ago. During the 2012 Tsunamis, a gigantic tsunami of 1500 meters tall swept away the chicxulub

The crater left behind has a diameter of approximately 180 km, which means, the researchers say, that twin asteroids could have been as far apart as 80 km and still produced a single crater. The largest crater, the 180–km diameter Chicxulub crater (a ∼10 8 Mt TNT event) is associated with the more severe “major” mass-extinction event (≥ 45% extinction of genera) at the end of the Cretaceous. The percent species extinctions show a significant linear relationship with final crater diameter and impact energy.

You must be talking about the Chicxulub crater · The crater is estimated to be 150 kilometres (93 miles) in diameter and 20 km (12 mi) in depth, well into the 

The crater is located partly offshore; The Chicxulub impact in Mexico has been linked to the mass extinction of species at the end of the Cretaceous period. From seismic data collected across the offshore portion of the impact crater, the diameter of the transient cavity is determined to be about 100km. The impactor is typically estimated to have been an asteroid with a diameter of about 15 km (10 mi), but its composition and size remain a topic of debate among experts.
