Search for the universe god

The good news is that the US Aerospace Agency (NASA) has found a 10,000th object near Earth, and the bad news is that there must be at least 100,000 unidentified candidates out there.

The near-earth object (NEO) is defined as asteroids and comets that reach a distance of 45 million kilometers from Earth while traveling in orbit around the sun. Most of the cosmic rocks and these ice blocks are harmless, they only fly near and maintain a fixed trajectory. NEO also has many sizes, from a few meters radius to real monsters like 1036 Ganymed, about 41km. And now, NASA has discovered the 10,000th NEO, a 300m-wide asteroid, named 2013 MZ5.

Director of the Observation of Near-Earth Objects (NEOO), Mrs. Lindley Johnson, said the determination of the 10,000th NEO is indeed a significant milestone. However, do not forget that there must be at least 10 times that number is out there, before people can reassure themselves that they have identified all 'gods' capable of destroying the earth, or at least is harmful to citizens on earth. The latest asteroid found by Pan-STARRS-1 glass telescope on Maui island in Hawaii, is part of the PanSTARRS sky survey campaign run by the University of Hawaii. The 2013 MZ5 is also not in danger and experts eliminate the possibility that it may threaten us in the future.

The appearance of the 2013 MZ5 is the latest discovery in the series of NEO search missions, mostly done by NASA during the past 15 years.'The first NEO was identified in 1898' , according to Space.com, quoted Don Yeomans, managing the NEO Program Office at NASA's Motivational Laboratory in Pasadena, California. 'Within a few hundred years, only about 500 NEO were found. But then, with the start of NASA's NEO observation program in 1998, we started tracking them from there. Along with the addition of new, more modern systems, the more we know about the NEOs present in the solar system, and where they will move in the future , 'Yeomans said.

Although there are still many cosmic rocks that have not been found, experts believe that the vast majority of the most massive and dangerous NEOs have been pulled into light. Of the 10,000 discoveries to date, about 1,000 NEO are larger than 1km. From this dimension onwards, when colliding with the earth, the consequences will be unimaginable, and all life on the planet's surface will be affected. Fortunately, no object of this size has yet to appear to be threatening the earth. The better news is that only a few dozen of the largest NEOs have yet to be discovered.

The smaller the NEO, the harder it is to find, which means that the majority of NEOs that have not yet been exposed are small in size, but not so that they are less dangerous. For example, any space rock that is 30 meters wide or more can cause significant damage to a residential area when it lands. So far, experts have only discovered less than 1% NEO from 30m or less. In 2005, the US Congress directed NASA to find 90% of NEOs of 140m or more size. This community is thought to be under 15,000 NEO of this size, and 30% of them have been followed.

Currently NEO programs are looking for new objects at an average rate of 3 NEO / day. However, what experts fear most is that the 'black horses' of meteorite exploded in the sky of Chelyabinsk (Russia) in February. first.
