Asteroid 2010 KQ: Probably a Rocket Body May 27, 2010 A small asteroid-like object has been discovered in an orbit about the Sun that is so similar to the Earth's orbit that scientists strongly suspect it to be a rocket stage that escaped years ago from the Earth-Moon system. Full Story

Asteroid 2010 GA6 To Fly Within Moon's Orbit on April 8, 2010 April 6, 2010 A newly discovered asteroid, 2010 GA6, will safely fly by Earth this Thursday at 4:06 p.m. Pacific (23:06 U.T.C.). At time of closest approach 2010 GA6 will be about 359,000 kilometers (223,000 miles) away from Earth - about 9/10ths the distance to the moon. The asteroid, approximately 22 meters (71 feet) wide, was discovered by the Catalina Sky Survey, Tucson, Az. Full Story

Small Asteroid 2010 AL30 To Fly Past The Earth January 12, 2010 Asteroid 2010 AL30, discovered by the LINEAR survey of MIT's Lincoln Laboratories on Jan. 10, will make a close approach to the Earth's surface to within 76,000 miles on Wednesday January 13 at 12:46 pm Greenwich time (7:46 EST, 4:46 PST).

Small Asteroid 2009 VA Whizzes By The Earth November 9, 2009 A newly discovered asteroid designated 2009 VA, which is only about 7 meters in size, passed about 2 Earth radii (14,000 km) from the Earth's surface Nov. 6 at around 16:30 EST. This is the third-closest known (non-impacting) Earth approach on record for a cataloged asteroid. Full Story

Asteroid Impactor Reported over Indonesia October 23, 2009 On October 8, 2009 about 03:00 Greenwich time, an atmospheric fireball blast was observed and recorded over an island region of Indonesia. The blast is thought to be due to the atmospheric entry of a small asteroid about 10 meters in diameter that, due to atmospheric pressure, detonated in the atmosphere with an energy of about 50 kilotons (the equivalent of 110 million pounds of TNT explosives). The blast was recorded visually and reported upon by local media representatives. See the YouTube video here A report from Elizabeth Silber and Peter Brown at the University of Western Ontario indicates that several international very-long wavelength infrasound detectors recorded the blast and fixed the position near the coastal city of Bone in South Sulawesi, island of Sulewesi. They note that the blast was in the 10 to 50 kT range with the higher end of this range being more likely. Assuming an estimated size of about 5-10 meters in diameter, we would expect a fireball event of this magnitude about once every 2 to 12 years on average. As a rule, the most common types of stony asteroids would not be expected to cause ground damage unless their diameters were about 25 meters in diameter or larger.
