The comet's head is green. This is a sign of diatomic carbon, C2, a gas which emits a verdant glow in the near-vacuum of interplanetary space. The comet's ion tail is blue. Once again, carbon is involved. One of the most abundant gases in comets is carbon monoxide (CO). When CO flows away from a comet's nucleus, it is ionized by solar UV radiation. Carbon monoxide ions (CO+) glow blue when they recapture electrons from the solar wind. The comet's dust tail is wan yellow. It is, simply, the color of sunlight reflected from comet dust.

*mag  = > light magnitude: Up to mag 3-4 stars are visible nearby cities with the naked eye, in very dark areas the seeing limit can reach up to mag 6-7.

The more higher numerical value is given, the more weaker are the objects. E.g. - 4,7 mag, Venus glittering; - 1,0 Sirius, brightest star; 3,5 M31 Andromeda, pale shiny oval)
