Astronomers from the SETI Institute, the NASA and the University of Curtin, are 75, the meteorite decreases, to many of the previously unlimited source areas in the main asteroid belt.

“This is a story of a decade of time, as every fall of the meteor registered is a new idea,” said Dr. Peter Geneskins, astronomer at the City Institute and NASA Research Center.
“We now have the first outline of a geological map of the asteroid belt.”
Ten years ago, Dr. Geneskins and his colleagues were aimed at building a network of full cameras in California and Nevada that could capture and follow the bright light of meteorites as they reached the Earth’s atmosphere.
“Others have built similar networks around the world, which together constitute the global fire ball Observatory,” said Hadrian Deviliboix, an astronomer at Curtin University.
“Over the years, we follow the course of 17 recovered meteorite waterfalls.”
“Several gunshots have been tracked by Doorbell and Dashcam video cameras from citizens worldwide and other custom networks.”
“In general, this research resulted in 75 meteorites made of laboratories with the orbit of the effect of the video and photographic cameras,” said Dr. Geneskins.
“This proves that it is sufficient to start seeing some patterns in the direction from which meteorites deals from the ground.”
Most meteorites arise from the asteroid belt, which is an area between Mars and Jupiter, where more than a million asteroids exceed 1 km of the sun.
These rocks arise from a small number of largest asteroids that were broken in the collision, as the debris fields are scattered in the area.
Even today, asteroids collide with the creation of debris fields within these asteroid families, which are called groups.
“We now see that 12 meteorites rich in iron -rich iron oven arose from a wreckless field called Koronis, which is located low in the main virgin belt,” said Dr. Geneskins.
“This meteorite has arrived from low -cost orbits with tropical periods consistent with this wreck.”
“By measuring the era of exposure to cosmic rays in meteorites, we can determine that three of these twelve meteors who grew up from the Karen group in Corones, which is 5.8 million years old, and two came from the Koronis2 group, with a dynamic age between 10 and 15 million years.”
“The last meteorite may measure the Koronis3 group: about 83 million years.”
The authors also found a group of Xondrit H on very slope orbits that appear to be created by the Nele Costeroid family in the central main belt, which is about 6 million years old.
Next ringing 3: 1 average movement with Jupiter can pump tendencies to that monitored.
A third group of H, which is about 35 million years old, originated from the internal main belt.
“In our opinion, this cartilage originated from the Massalia asteroid family in the main inner belt because this family has a group of the same dynamic age,” said Dr. Geneskins.
“The asteroid that created that mass, the asteroid (20) Masalia, is the body of the HHordrite type.”
The researchers found that the low -iron (LL Chondrite) comes to us primarily from the internal main belt.
“We suggest that maturity from the Hirstha family as a asteroid is located over the Masalia family,” said Dr. Geneskins.
“Corbps Hirsta does not seem like her debris.
It is important to know from any debris field in the asteroid belt that our meteorites create for planetary defense efforts against asteroids near the ground.
The approach of the antermour caner can provide evidence of its origin in the asteroid belt in the same way as the orbits of the meteorite.
“The asteroids near the Earth do not reach the same orbits as meteorites, because it takes longer until this develops to the Earth,” said Dr. Geneskins.
“But they come from some of the same as the families of the asteroid.”
