Will the icy visitor survive? The drama will play itself out in the hours ahead.

This kamikaze comet is probably a member of the Kreutz sungrazer family. Named after a 19th century German astronomer who studied them in detail, Kreutz sungrazers are fragments from the breakup of a giant comet at least 2000 years ago. Several of these fragments pass by the sun and disintegrate every day. Most are too small to see. Today's fragment is a big exception.

Credit: The comet was found on Jan. 2nd by Australian amateur astronomer Alan Watson, who was inspecting images obtained by STEREO-A's Heliospheric Imager on Dec. 30, 2009.
