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 town was established in 1876 on a farm called Visgat, on the Vredefort impact structure, the largest and oldest visible bolide impact crater in the world (with a diameter of 300 kilometres (190 mi)).
Area code 806 is a telephone area code in the North American Numbering Plan (NANP) for the U.S. state of Texas in the Panhandle and South Plains, including the cities of Amarillo and Lubbock. It was created in 1957 in a flash-cut from numbering plan area (NPA) 915, the north-western corner of the state, but also incorporated a small portion of ...
In 1947, the American Telephone and Telegraph Company (AT&T) devised the first nationwide telephone numbering plan and assigned the original North American area codes. The state of California was divided into three numbering plan areas (NPAs) with distinct area codes: 213, 415, and 916, for the southern, central, and northern parts of the state ...
Sudbury Basin is the third-largest crater on Earth, after the 300 km (190 mi) Vredefort impact structure in South Africa, and the 180 km (110 mi) Chicxulub crater under Yucatán, Mexico. Geochemical evidence suggests that the impactor was likely a chondrite asteroid or a comet with a chondritic component.
A schematic diagram of the area surrounding the Vredefort Dome, where a massive meteor created an impact crater 300 km in diameter 2020 million years ago. The red dot represents the point of impact. The outer circle has a radius of 150 km, and indicates the approximate location of the crater rim.
