[6] while a 10-meter (33 ft) asteroid falling over Earth is unlikely to reach the surface intact before being destroyed in a meteor air burst, [7] a 10-meter (33 ft) asteroid falling over Mars may leave a crater over 100 meters (330 ft) across, [8] or several smaller craters tens of meters across.

Analysis of the Hiawatha Glacier reveals the presence of a 31 km wide impact crater dated at 58 million years of age, less than 10 million years after the Cretaceous–Paleogene extinction event, scientists believe that the impactor was a metallic asteroid with a diameter in the order of 1.5 kilometres (0.9 mi). The impact would have had global ...
A 2017 study dated them to at least four different eruptions from 1416 ± 7 Ma to 1322 ± 10 Ma. [2] It has been shown that the nakhlites were suffused with liquid water around 620 million years ago and that they were ejected from Mars around 10.75 million years ago by an asteroid impact. They fell to Earth within the last 10,000 years. [1]
Before the new study the location of the crater caused by the impact was unclear. Mars mega-tsunami may have been caused by asteroid strike, study suggests Skip to main content
The fossils were between 35.5 to 35.9 million years old and were found in a nearly 10-foot-long rock core: a tube-like sample taken from underneath the Gulf of Mexico by the scientific Deep Sea ...
It has been shown that the nakhlites were suffused with liquid water around 620 million years ago and that they were ejected from Mars around 10.75 million years ago by an asteroid impact. They fell to Earth within the last 10,000 years. [21]
NASA’s Perseverance Mars rover used its right-front navigation camera to capture this first view over the rim of Jezero Crater on Dec. 10, 2024, the 1,354th Martian day, or sol, of the mission.
The lunar cratering record suggests that the rate of impacts in the Inner Solar System 4000 million years ago was 500 times higher than today. [44] During the Noachian, about one 100-km diameter crater formed on Mars every million years, [3] with the rate of smaller impacts exponentially higher.
