Update about 213P-B fragment

MPECs 2011-P25, 2011-P37 and CBET 2798 detailed the discovery and follow-up about a secondary nuclear condensation (component B) of comet 213P/Van Ness. Recently we performed some additional follow-up on it, in order to check its evolution.

Comet Elenin Poses No Threat to Earth

Often, comets are portrayed as harbingers of gloom and doom in movies and on television, but most pose no threat to Earth. Comet Elenin, the latest comet to visit our inner solar system, is no exception. Elenin will pass about 22 million miles (35 million kilometers) from Earth during its closest approach on Oct. 16, 2011.

SOHO Watches a Comet Fading Away

NASAs EPOXI spacecraft came within 450 miles of Comet Hartley 2, a small comet not even a mile in diameter, which takes about six and a half years to orbit the sun. Designated officially as 103P/Hartley 2, the comet thus became the fifth for which scientists have collected close-up images.
