Conventional wisdom around space rocks and asteroids may now be challenged with the discovery of a massive meteorite fragment the size of a beach ball. The meteorite was found in one of the world's largest impact craters, the Morokweng crater in the North West province.

An unidentified green object streaked across the Queensland sky last night, before landing on a property between Toowoomba and Warwick near the Great Dividing Range.
Farmer Don Vernon lives on the property next to where the object hit the ground, and watched it come in to land.
"I was finished on the farm and driving home, and as I came in the gate I faced this enormous green ball of light with a white centre.
SOUTH-east Queensland residents have been startled by a bright, green ball of streaking light that initially sparked fears of a plane crash.
A police spokeswoman said the suspected meteor was seen travelling east to west in the region from Bribie Island, across the Sunshine and Gold Coasts as far inland as Warwick.

May 5, 2006 -- If you saw a bright light in the sky Thursday night, you're not alone.
Astronomers said a large meteor shower crossed straight over El Paso just before 9:45 p.m. Thursday.
One meteor was so large that it cast an orange glow against the mountain.
Pasadena CA - NASA said Thursday there is no danger that Comet 73P/Schwassmann-Wachmann 3 - or any of its many fragments - will strike Earth during its closest approach next month. To provide further reassurances, the agency has employed the Hubble Space Telescope to take high-resolution images of the approaching object, and will soon follow suit with Spitzer to observe the fragments in infrared light.
"We are very well acquainted with the trajectory of Comet 73P Schwassmann-Wachmann 3," said Don Yeomans, manager of the agency's Near-Earth Object Program, at Jet Propulsion Laboratory. "There is absolutely no danger to people on the ground or the inhabitants of the International Space Station, as the main body of the object and any pieces from the breakup will pass many millions of miles beyond the Earth."
Comment: None of this hoopla has happened before when a comet when sailing by the planet. NASA just stated it wasn't a threat, and that was that. If they are so confident that none of the 73P fragments will hit, why are they scrambling all their resources this time "to provide further reassurances"??
You do not have to look to the outer edges of the solar system, or even out beyond Neptune to observe a reservoir of comets. A bevy of the ice-containing bodies lies disguised as main-belt asteroids between Mars and Jupiter, claim astronomers from the University of Hawaii, US.
David Jewitt and Henry Hsieh have dubbed the new population "main belt comets". They describe three objects with near circular, flat orbits in the asteroid belt that stream volatile materials, producing an observable tail for weeks and months at a time.
The finding backs a theory that ice-bearing asteroids - or "comets" - from this much closer region may have played an important role in forming the Earth's oceans.
Astronomical observatories have received a number of reports of a fireball, described as flashing orange or blue, seen in the skies over the Kanto region around 8:30 p.m. Wednesday.
A TOP Russian scientist has suggested that global warming was started by a meteor that exploded in the atmosphere nearly 100 years ago.
Scientists have long known that a major ingredient in comets is water ice, but they were unsure whether the ice was contained mainly inside or if it could be found on the surface as well.
A new analysis of data from NASA's Deep Impact mission last year provides the first evidence that water ice can indeed exist on a comet's exterior.
People looking to the sky Wednesday morning got a special treat. A fireball appeared in the sky south of Calgary just before seven o'clock. It moved quickly from east to west before it burned out. Witnesses say it broke into pieces when it flared out.
Several people have reported the fireball to University of Calgary professor Alan Hildebrand. He's hoping that someone close to where the fireball exploded, saw it, or heard the sonic boom, will call in. That will help locate pieces of the meteorite.
