April 13 – The asteroid99942 Apophis (previously better known by its provisional designation 2004 MN4) will pass within 30,000 km (18,600 mi) of the Earth, very briefly appearing as bright as 3rd magnitude. A possibility exists that Apophis could go through a 400 m wide "keyhole" on this pass which would put it on a collision course with the Earth in 2036.
