The impact distorted the Witwatersrand Basin which was laid down over a period of 250 million years between 950 and 700 million years before the Vredefort impact. The overlying Ventersdorp lavas and the Transvaal Supergroup which were laid down between 700 and 80 million years before the meteorite strike, were similarly distorted by the ...
The Witwatersrand Basin is a largely underground geological formation which surfaces in the Witwatersrand. It holds the world's largest known gold reserves and has produced over 40 000 tonnes (1.3 × 10 9 ozt), which represents about 22% of all the gold accounted for above the surface. [ 3 ]

When a cruise liner-size asteroid comes within 19,883 miles (32,000 kilometers) of Earth on April 13, 2029, it won’t be alone.
Less than ten thousand years old, and with a diameter of 100 m (330 ft) or more. 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]
The Torino scale is a method for categorizing the impact hazard associated with near-Earth objects (NEOs) such as asteroids and comets.It is intended as a communication tool for astronomers and the public to assess the seriousness of collision predictions, by combining probability statistics and known kinetic damage potentials into a single threat value.
2024 BX 1 is the eighth asteroid discovered before impacting Earth, and is Sárneczky's third discovery of an impacting asteroid. Before it impacted, 2024 BX 1 was a near-Earth asteroid on an Earth-crossing Apollo-type orbit. The bolide was studied in June 2024. It had a steep entry of 75.6° and an entry speed of 15.20 km/s.
2023 NT 1 is a near-Earth asteroid, approximately 30 meters in diameter, [3] that passed within 1/4 lunar distances on July 13, 2023.. It was not discovered until 2 days after closest approach due to coming from the daylight direction.
