2009 DD45
Template:Downsize 2009 DD45 is a small Apollo asteroid [1] that passed near Earth at an altitude of 63,500 km on 2 March 2009 at 13:44 UTC, discovered on 28 February 2009, only two days before its closest approach to the Earth. [2] [3] Its estimated diameter is between 21 and 47 meters. [1] The BBC cited the minimum distance as 72,000 km (44,750 miles) (about .2 lunar distances). [4]
This is about the same size as the object that caused the Tunguska event in 1908. [4]
It passed farther away (40 thousand miles versus 4 thousand miles) but was substantially larger then 2004 FU162, a small asteroid about 6m (20ft) across which came within about 6,500km (4,000 miles) in 2004.[4], and is more similar in size to 2004 FH.
