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 ]
2024 UQ, designated formerly as A11dc6D, was a one-meter meteoroid that struck the Earth's atmosphere and burned up harmlessly on 22 October 2024 above the Pacific Ocean off the coast of California. 2024 UQ is the tenth impact event that was successfully predicted, which was discovered by the ATLAS survey.

From Witwatersrand University 1989: Honorary member of the Astronomical Society of Southern Africa [ 11 ] 1989: An asteroid discovered in 1986 in the main belt is given the official designation (4093) Bennett after John C. Bennett.
99942 Apophis (provisional designation 2004 MN 4) is a near-Earth asteroid and a potentially hazardous object, 450 metres (1,480 ft) by 170 metres (560 ft) in size, [3] that caused a brief period of concern in December 2004 when initial observations indicated a probability of 2.7% that it would hit Earth on Friday, 13 April 2029.
In 2006, an asteroid was named after Köberl. In 2007, he received the Barringer Medal of the Meteoritical Society , its highest award for research related to impact cratering studies. From 2007 to 2010, Köberl served as Visiting research professor at the Department of Earth Sciences and the Planetary and Space Science Research Institute, Open ...
They showed that the near-Earth asteroid 1994 CC is a triple system, which encountered Earth within 2.52 million kilometers on June 10, 2009. This relatively close approach to Earth made the discovery possible, as before the approach, scientists knew very little about this asteroid.
