Sites of astronomical interest

Tswaing (Soutpan) Meteor Crater

Located about 40km north of Pretoria, west of Hammanskraal, off the M35 Soutpan road. This crater is the result of a meteoritic impact about 220 000 years ago and is 1.1 km in diameter, comparable in size to the much better-known Barringer meteor crater in Arizona, USA. The Tswaing site is controlled by the Northern Flagship Institution (museum). Open to the public, with an interpretative centre.

Robert Groess and Trevor Gould (ASSA Johannesburg Centre) visited Tswaing in September 2005. Read Robert's account and browse his photographs of the trip.
