The Charlottetown meteorite was a meteorite fall observed on July 25, 2024. It is notable as the only meteorite known with video and audio of the impact recorded, and as the only known meteorite fall in Prince Edward Island. [2] The Charlottetown meteorite is classified as H5 ordinary chondrite. [1]
This list includes all 60 confirmed impact structures in North America in the Earth Impact Database (EID). These features were caused by the collision of large meteorites or comets with the Earth.
The projectile was probably a stony asteroid, at least 2 kilometres (1.2 mi) in diameter, and weighing an estimated 15 billion tonnes (17 billion short tons). The Mont des Éboulements, situated in the exact centre of the impact structure, is interpreted as the central uplift, a consequence of elastic rebound. [3]
The event Raisani describes is known as the Chelyabinsk meteor, which began as an asteroid that entered Earth's atmosphere on Feb. 13, 2013, at approximately 60 ft. in diameter and weighing 10,000 ...
Geologists reached consensus by about 1970 that the Sudbury basin was formed by a meteorite impact. [citation needed] In 2014, analysis of the concentration and distribution of siderophile elements as well as the size of the area where the impact melted the rock indicated that a comet rather than an asteroid most likely caused the crater.

The Younger Dryas impact hypothesis (YDIH) proposes that the onset of the Younger Dryas (YD) cool period at the end of the Last Glacial Period, around 12,900 years ago was the result of some kind of cosmic event with specific details varying between publications. [1]:
The Pingualuit Crater (French: Cratère des Pingualuit; from Inuit "pimple"), [2] formerly called the "Chubb Crater" and later the "New Quebec Crater" (French: Cratère du Nouveau-Québec), is a relatively young impact crater located on the Ungava Peninsula in the administrative region of Nord-du-Québec, in Quebec, Canada.
It was the most powerful asteroid strike in more than 100 years, and left around 1,500 people injured as well as causing significant damage to buildings and blowing out windows. Show comments ...
