Arecibo Observatory Finds Asteroid 2012 LZ1 To Be Twice As Big As First Believed
Using the planetary radar system at Arecibo Observatory, astronomers have determined that asteroid 2012 LZ1 is twice as large as originally estimated based on its brightness, and large enough to have serious global consequences if it were to hit the Earth. However, a new orbit solution also derived from the radar measurements shows that this object does not have any chance of hitting the Earth for at least the next 750 years. Read more
Asteroid Near Earth Fly-By Captured By Italian Observatory
Asteroid 2012 LZ1 came about 3.3 million miles from planet Earth on its closest approach on June 14th, 2012. The space rock is about 1640 feet wide. The Remanzacco Observatory captured imagery.
The asteroid, which is 10 times the size of an Olympic swimming pool, is one of 9,000 "near-Earth objects" recorded by Nasa. It will not be visible to the naked eye but stargazers can watch a live broadcast and catch a glimpse of it passing by Earth online. Named LZ1, the asteroid is 500m wide and is likely to get only within 14 times the moon's distance from Earth. Read more
