Comet Holmes (17P/Holmes) in the constellation of Perseus,optical image. The comet is visible as sunlight reflects off its coma,a dusty cloud surrounding the nucleus (bright,centre). By late November 2007 the coma had swollen to a diameter of over 1.4 million kilometres (larger than the Sun),an expansion thought to have resulted from a fragment breaking away from the comet and disintegrating. Comet Holmes is a short-period comet,with an orbit of only 6.9 years. Photographed on 19th November,2007 | |
