Meteorite fall statistics are frequently used by planetary scientists to approximate the true flux of meteorites on Earth. Meteorite falls are those meteorites that are collected soon after being witnessed to fall, whereas meteorite finds are discovered at a later time. Although there are 30 times as much finds than falls, their raw ...

This is a list of largest meteorites on Earth. Size can be assessed by the largest fragment of a given meteorite or the total amount of material coming from the same meteorite fall: often a single meteoroid during atmospheric entry tends to fragment into more pieces. The table lists the largest meteorites found on the Earth's surface.
Harvard researchers found that when a meteorite nicknamed S2 paid a visit to our planet 3 billion years ago, it may have helped life flourish. Giant meteorite that hit Earth 3 billion years ago ...
Findings could help shed light on how life came to exist on Earth.
Asteroids with a 1 km (0.62 mi) diameter strike Earth every 500,000 years on average. [20] [21] Large collisions – with 5 km (3 mi) objects – happen approximately once every twenty million years. [22] The last known impact of an object of 10 km (6 mi) or more in diameter was at the Cretaceous–Paleogene extinction event 66 million years ago.
The Karin family, formed 5.8 million years ago, and the Koronis family, formed 7.6 million years ago, account for a class of meteorites called H chondrites that represent 33% of known Earth ...
Each year, the Earth is hit by 5 m (16 ft) diameter meteoroids that deliver an explosion 50 km (31 mi) above the surface with the power equivalent of one kiloton of TNT. [6] The Earth is hit every day by a meteor less than 5 m (16 ft) in diameter that disintegrates before reaching the surface. The meteors that do make it to the surface tend to ...
