2005 NB56
From Wikipedia, the free encyclopedia
2005 NB56, also written as 2005 NB56, is a near-Earth asteroid of the Apollo group.[2] In 2009, research physicist Edward Drobyshevski and colleagues have suggested that 2005 NB56 could be a possible source of the meteoroid that caused the Tunguska event on 30 June 1908. It has been also suspected to be a dormant comet.[4]
