Chicxulub impactor Chicxulub impactor The Chicxulub impactor ( ), also known as the K/Pg impactor and (more speculatively) as the Chicxulub asteroid, was an asteroid or other celestial body some in diameter which struck the Earth at the end of the Cretaceous period, approximately 66 million years ago, creating the Chicxulub crater. It impacted a few miles from the present-day town of Chicxulub in Mexico, after which the impactor and its crater are named. Because the estimated date of the object's impact and the Cretaceous–Paleogene boundary (K–Pg boundary) coincide, there is a scientific consensus that its impact was the Cretaceous–Paleogene extinction event
Haughton impact crater at crater sites on a cold, wet Mars. The Mars Institute and the SETI Institute operate the Haughton–Mars Project at this site, designed to test many of the challenges of life and work on Mars. The non-profit Mars Society also operates the Flashline Mars Arctic Research Station (FMARS) at this site and conducts similar research. Haughton impact crater Haughton impact crater is located on Devon Island, Nunavut in far northern Canada. It is about in diameter and formed about 39 million years ago during the late Eocene. The impacting object is estimated to have been approximately in diameter. Devon Island
