Scientists have released an analysis of a meteorite fragment gathered after a 2008 asteroid near-collision with Earth. They show the parent asteroid was huge, and the results suggest that special, water-holding type of asteroids can be larger and have different mineral compositions than previously thought. Advertisement The study’s findings were published this week in the journal Nature Astronomy and look at the chemical composition of a sliver of those meteorite fragments. The story of the fragments begins in October 2008, when scientists became aware of an asteroid on a collision course w...
While other astronomers are scanning deep space for signs of the existence of the mythically theoretical Planet Nine, a group of researchers in Colorado has been looking down instead of up and found evidence in a meteorite of what may have been a small planet in the early days of our solar system. Is it still around? Can it help find Planet Nine? If it’s designated a planet, will Pluto be upset? “Carbonaceous chondrite meteorites record the earliest stages of Solar System geological activities and provide insight into their parent bodies’ histories.” According to a new study published...

An asteroid that exploded in Earth's atmosphere in 2008 was part of a much larger space rock that once contained water, a new study reveals. The asteroid, called 2008 TC3, lit up the skies of Sudan in October 2008 and showered the ground with 600 meteorites, known collectively as Almahata Sitta. After analysing a fragment of Almahata Sitta, US researchers found evidence that it came from a large, water-rich parent asteroid roughly the size of a dwarf planet – anywhere from 400 to 1,100 miles (640 to 1,800 kilometres) in diameter. Experts believe the parent body formed in the pres...
