令人惊奇的是，除有一个正常彗尾外，彗星还有一个逆向彗尾，指向太阳方向。
Comet C/2002 T7 (LINEAR) imaged April 17.796 UT, 2004. 4 x 30 sec exposures were stacked for this 13?wide FOV (with south to right). A Canon EOS 300D at ISO 400 and a 100mm f2.8 lens (Wide open) was used. A magnified view of the comet from the same image is shown in the insert. Note twilight was well advanced when this image was taken |
