This image from March 3, 2002 captured the
active
comet's bright, condensed coma and
a delightful array of subtle structures in its developing
tail. The tail stretches for 5 degrees or so against a background of stars in the constellation Pisces. Cataloged as comet C/2002 C1,
improved orbit determinations now
make it seem very likely that Comet
Ikeya-Zhang has been around here before. Refined
calculations
indicate this comet's last trip through the
inner Solar System was 341
years ago, in 1661,
when it was
recorded as a
bright comet.
