Astronomers revealed that a large explosion occurred in the waters of the Gulf of Bone, South Sulawesi Indonesia on October 8, 2009 is the result of a meteorite falling to earth from an asteroid about 10 meters in diameter.
"The explosion occurred due to atmospheric ressure causes the release of considerable energy, where the meteorite fall rate of about 20.3 km per second or 3,080 km per hour," said astronomers from the institute of Aviation and Space Agency (Lapan) Dr Thomas Djamaluddin in Jakarta , Tuesday (27/10).
International monitoring system to ban nuclear testing from 11 stations, reported having detected a large explosion that centered around the latitude and longitude 4.5 LS 120 BT, around 11:00 am on October 8. Blast analysis showed that the explosive force of about 50 kilotons of TNT (Trinitrotoluene) and signals the explosion which also reached the high stratosphere more than 20 km.
Meteor explosion in Bone, South Sulawesi, on October 8 and worldwide scientific attention. The explosion triggered a large asteroid was even reported to be detected by the alarm's infrasound Comprehensive Nuclear Test Ban Treaty Organization (CNTBTO), a distance of 10,000 km from the location of the meteorite fall.
As reported Spaceweather.com, a large explosion in the collapse of Bone confirmed asteroid 10 meters in diameter. Power of the explosion, according to researchers from the University of Western Ontario, Elizabeth Silber and Peter Brown, equivalent to 50 kilotons of TNT bombs. Or, two to three times more powerful than the atomic bomb blast that occurred in World War II.
To the point, this explosion was detected by the sensor that is dedicated CNTBTO detect the activity or nuclear explosion on earth. The explosion was very surprised astronomers world. Because, they did not detect the existence of this asteroid before digging the earth.
Most asteroids that fell did not cause damage on Earth, but its diameter reaches more than 25 meters. Djamal say, based on the estimated distribution of meteoroids, asteroids in the space near Earth, such objects have probably fallen on the earth every 2 to 12 years.
On Thursday (8 / 10), citizen Bone, South Sulawesi, were startled by the sound of the explosion in which several witnesses had seen the object emits fire and smoke in the air.
