About #15# kiolmeters on the Yucatan Peninsula in Mexico near the town of Chicxulub almost #65# million years ago.

Explanation:

The biggest meteor to ever hit earth is believed to be the one that hit the Earth almost #65# million years ago on the Yucatan Peninsula in Mexico near the town of Chicxulub and left behind a crater more than #180# kilometers in diameter and #20# kilometers in depth.

The meteor is estimated to be of diameter of #15# kilometres and delivering an estimated energy of 10 billion Hiroshima A-bombs. The impact would have caused a tsunami of a few kiolmetres. The emission of dust and particles could have covered the entire surface of the Earth for several years, possibly a decade, creating a harsh environment for living things. Many scientists believe that the meteorite that left this crater caused or contributed to the extinction of the dinosaurs.
