Asteroids the size of the 2012 LZ1 Twice Greater than Expected.
Asteroid 2012 LZ1 which recently passed close to Earth known to have a size two times larger than expected. Asteroid 2012 was discovered by Rob McNaught LZ1 at Siding Spring Observatory in Australia. Initially the size of the asteroid was estimated to 502 meterr, but by using planetary radar system, known asteroid the size of about 1 km. By considering the size of the asteroid, scientists can predict what will happen if an asteroid were to hit Earth.
“The object is larger than expected, said Dr. Ellen Howell of Arecibo,” It is important to know how the radar system works, because we still have to figure out how much the population of asteroids that cross Earth’s chances, “he added, as quoted astronomi.us of universetoday.com, Friday (06/22/2012).
Asteroid 2012 LZ1 would pass close to Earth again on June 12, 2053 after which it will move away and no longer pose a threat to Earth, at least for the next 750 years. It was obtained by using a sensitive planetary radar system that monitors all about the asteroid. Asteroid 2012 LZ1 known to have a surface that is very dark and reflects only 2-4% of the light it receives.
