quote:ASTEROID FLYBY: Newly-discovered asteroid 2011 AN52 is flying past Earth today just inside the orbit of the Moon (0.8 LD). The space rock is only 8 meters wide, about the size of a small room, so even experienced amateur astronomers will have trouble photographing it as it zips through the northern constellations Draco and Cygnus glowing like an 18th magnitude star. But it is there
quote:Comet Elenin was just discovered this past Dec. 2010 by a Russian Astronomer Leonid Elenin. The question is why media hasn’t said anything about it? They have always made a big fuzz in the past about found comets. Is it because it is going to be coming a little too close for comfort and they don’t want people freaking out? Comet Elenin Could Hit Earth. This is a possibility because of the very unstable predictions of the Comet. Preliminary predictions have Comet Elenin coming within 42 million miles of the Earth with a very favorable comet sun angle for observers in the northern hemisphere. This is likely to change somewhat as additional data will tweak the orbit, but as it stands now we will see a spectacular comet in late October or early November 2011. When Comet Elenin first was discovered in December last 2010 it was calculated to pass 8.8 Au (8.8 times the distance of the Sun form us) away. But now these calculations has once changed again. Today the orbital calculation is down to 0.24 Au with a minimum as low as 0.15. But these data is being recalculated all the time and it could get even closer but that depends what it encounters in the Oort belt. Just so you know the Moon is 0.00256 away from us to give you a comparison. We must be aware the this comet could bring enormous amount of debris with it and Earth will pass through the debris trail. This will probably take place around the 6th November 2011 or later.
quote:Russian astronomers predicted Apophis may strike Earth on April 13, 2036"Apophis will approach Earth at a distance of 37,000-38,000 kilometers on April 13, 2029. Its likely collision with Earth may occur on April 13, 2036," Professor Leonid Sokolov of the St. Petersburg State University said.The scientist said, however, the chance of a collision in 2036 was extremely slim saying that the asteroid would likely disintegrate into smaller parts and smaller collisions with Earth could occur in the following years."Our task is to consider various alternatives and develop scenarios and plans of action depending on the results of further observations of Apophis," Sokolov said.The asteroid, discovered in 2004, is considered the largest threat to our planet, although NASA scientists reduced the likelihood of a hazardous strike with Earth in 2036.Russia's space agency announced its plans earlier to consider a project to prevent the large asteroid from colliding with Earth

According to JPL's Near Earth Object Program office, the meter-wide space rock was only 5480 km (0.85 Earth radii) over the Pacific Ocean at closest approach. That makes it the nearest non-impacting object in their catalog. The encounter was so close, Earth's gravity altered the course of the asteroid by a whopping 60 degrees.Full story[ link | afbeelding ]Trajectory of Asteroid 2011 CQ1 - February 4, 2011

A subsequent attempt by theAmerican Museum of Natural History to obtain theHoba Meteorite for its display also came to nothingbecause of transport difficulties, after which it wasdeclared a National Monument in 1955.Surprisingly, no crater or altered rocks have been found at the impact site, which together with the merefact of its survival as a single mass, suggests a low angle of atmospheric entry and a fairly low velocity toallow a soft landing. During its passage through the Earth's atmosphere melting caused the shallow pitsand depressions on the meteorites upper surface.

quote:Fireball in the skies over Salem County?It’s a bird, it’s a plane ... no it’s a meteorite?If you were lucky enough Monday, at around 12:45 p.m., you looked to the skies over Salem County and saw a majestic, flaming fireball falling through the atmosphere.“So far we have 30 reports of a fireball moving in a general west to east direction as seen from the northeastern United States,” said American Meteor Society official Robert Lunsford Monday afternoon. “Daylight fireballs are rare and must be exceedingly bright to be noticed with the sun in the sky.”One sighting happened right here in Salem County.Woodstown resident Walt McGuniess called the Sunbeam and described the meteorite as it flew over top of Woodstown High School.“I was out on a walk with my son and then I looked over top of Woodstown High School and this huge meteor came hurdling through the sky,” said McGuniess. “It was spectacular, like a huge fireworks display.”Lunsford called it a random event.“This was most likely a random event not associated with any known meteor shower,” said Lunsford. “This object was most likely the size of a small car before striking the upper atmosphere (and beginning to burn up).”Lunsford said the fireball terminated over the Atlantic Ocean.“There is no hope for recovering any possible debris,” he said.A Ridgefield Park man said he saw the fireball after glancing out a window during a break from his work Monday. HL Devore works at GalleryCollection.com in North Jersey. “It was an amazing sight. I have never seen anything like it,” said Devore. “Their was a flash of light then a trail of smoke.”Devore took to the computer and as with most types of technology these days the work spread.Descriptions of sightings exploded on the social networking websites Twitter and Facebook. Posts came from people in New Jersey, Philadelphia, Connecticut, New York and even Egypt.
