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.
Researchers at University New South Wales (UNSW) believe they’ve found evidence that an asteroid impact buried near the town of Deniliquin, Australia, is the world’s largest ever discovered ...
The Vredefort impact structure is the largest verified impact structure on Earth. [1] The crater, which has since been eroded away, has been estimated at 170–300 kilometres (110–190 mi) across when it was formed. [2] [3] The remaining structure, comprising the deformed underlying bedrock, is located in present-day Free State province of ...

The EID lists fewer than ten such craters, and the largest in the last 100,000 years (100 ka) is the 4.5 km (2.8 mi) Rio Cuarto crater in Argentina. [2] However, there is some uncertainty regarding its origins [ 3 ] and age, with some sources giving it as < 10 ka [ 2 ] [ 4 ] while the EID gives a broader < 100 ka.

Ceres is the largest asteroid in the main asteroid belt. [16] It has been classified as a C‑type or carbonaceous asteroid [16] and, due to the presence of clay minerals, as a G-type asteroid. [60] It has a similar, but not identical, composition to that of carbonaceous chondrite meteorites. [61]
