11 metre asteroid 2010 AL30 to swing by the Earth on Wednesday

Wednesday, January 13, 2010

March 2009 was a big month for asteroids coming out of nowhere to graze the Earth, and there were a few more throughout the year as well. Looks like 2010 is starting off big with an asteroid called 2010 AL30 which will pass by at a distance just one third that from the Earth to the Moon. The trajectory of this asteroid can be seen here:



Compare just how close this is with other near-Earth approaches in the next few days (LD = Lunar Distance, the distance from Earth to the Moon):

There seems to be an error in the chart on 2010 AL30 though as it should be as bright as a 14th magnitude star, not 26.2.
