25 m wide meteorite stray Earth Halloween nightEarly warning system the meteorites of the Aeronautics and Space Agency (NASA) discovered a 25-metre diameter meteorite close to Earth on the night of October 31.Meteorites Earth flyby Halloween last night after new space monitoring system called the NASA Scout determine how these 5 days, according to the Mirror.A telescope in Hawaii detected the object for the first 25 minutes. The data uploaded to the Scout system allows the software to predict the route of the meteorites within 10 minutes, including the route to collide with the Earth. Scout immediately notify three different telescope continues to observe, the exclusion of the possibility and the last confirmed meteorite will fly through the Earth is safe.Meteorite Halloween had up to 25 m fly close to Earth at a distance of 498,897 km, which is about 1.3 times the distance from the Earth to the moon."When a first telescope detected the object is moving, all you know is just a small dot moving across the sky. You do not have the information it in how far ", astronomer Paul Chodas at the Jet Propulsion Laboratory of NASA, who runs the program, the Scout said. "The more you driven many telescopes on the object, the more you acquire more data, so be sure of the size and direction of it. But sometimes you don't have much time to make these observations ".Scout is designed to track objects near the Earth and potentially impacting the planet so that NASA can act promptly. The system is in test phase and meteorites Halloween is the first case discovered Scout. This system will officially go into operation later this year."If known in advance, you can divert the meteorite using a small explosion when it is at a distance of billions of km before crashing into the Earth", Ed Lu, head of the Organization to prevent the risk from meteoroid B612, said
