According to local people, they heard small explosions appear a few days before they appeared.

Local police representative Paul Ludik also added that these metal balls weigh about 6kg. They were found to be located about 17.7m away from where it landed, where a hole was about 3.6m deep and wide due to their impact.

The appearance of some similarly shaped and sized balls has been recorded in South Africa, Australia and the Americas for the past 20 years. However, there is no exact explanation for their origin.

According to local authorities in Namibia, the ball was discovered in mid-November 2011, but the local government conducted a pre-check before announcing the discovery and notification to NASA.

In addition, they fell into remote areas, so there was no injury to humans, the possibility that they were explosive devices was eliminated.
