Earth’s closest encounter to asteroid this Monday
NASA has announced that the earth had its closest so far encounter to an asteroid this Monday afternoon. The experts estimated that the 2011 MD asteroid would be so close to our planet that its trajectory would be changed by Earth’s gravity force. NASA assured people they didn’t need to worry as it posed no danger.
We just witnessed one of the rarest moments in the history of mankind and of our planet. NASA recently discovered an asteroid was expected to pass within 7,600 miles of Earth. The asteroid is between 16 and 60 feet wide and was first seen on Wednesday through a robotic telescope in Mexico, United States. The International Astronomical Union’s Minor Planet Center in Massachusetts released the news on Thursday.
The trajectory of the asteroid
The asteroid passed over the southern area of the Atlantic Ocean, near the coast of Antarctica. It passed around 16.00 GMT. The event could be seen in several parts of the world. The Sky & Telescope magazine said that the father south you are, the better you can see it and the farther west you are within the southern zone the shorter the sight will be. However, from this part of the world, you could have taken the closest look at the asteroid as it passed the Earth. “The asteroid peaks brighter than magnitude 11.0 at the places where the closest approach is visible, and it’s already about magnitude 12.5 — fairly easy to spot in an 8-inch telescope — by 14:30 UT, 2½ hours before closest approach.”
The first forecasts of the experts said that 2011 MD will be pass 100 miles closer to earth and 3 and a half hours sooner. The asteroid has been seen from South Africa, Antarctica, Southeast Asia, Eastern China, Japan, Australia, New Zealand and all Western Pacific.
Previous asteroid encounters
Minor Planet Center says that according to its charts, this is the fifth recorded asteroid that passed so close to our planet. The last one was sighted June 2, this year. It was 10 metre wide and passed between the moon and the earth. Another one was detected October 7 2008, a few hours before burning up in the atmosphere. The “2008 TC3” was best seen from Sudan. Other asteroids have been recorded in January 2009, May 2009 and September 2010.
its fantastic to have all this available technology to spot such threats to our survival on this planet,but what is our reaction to an asteroid on course with earth?i hope the powers that be have it under control-else we could be 'toast'you'd have to have a certain amount of people of different races to be able to leave before the inevitable hit earth,tho i did hear there was a space-station on the moon,hopefully it is well advanced for the chosen few,we are amazing us humans -i just hope we don't try the destructive path we have taken against our own kind on other unknown beings-else wed really be pushing our luck!the thoughts and possibilities are to much too think about,im just happy to be alive now and witness these great new discoveries.go hard NASA
