- since their formation, and their nuclei are thought to preserve physical and chemical information about the early solar nebula. When a comet approaches the Sun, the ices contained in the nucleus sublimate, and complex molecules are released into the coma. These molecules, the parent species, can be observed in the infrared and radio domains .Comets images that recorded, by CCD camera a lot of information about the molecular interaction that carried out inside the comet due to the after of the sun and the atmosphere. The differences of photonic intensity can give us a curve which appears from any line of this image. While the equations can get upon special relation for temperature distribution, Velocity distribution, Distribution of density and density number distribution which give number of particles per unit volume. The interaction between cemetery tail ions and solar wind can be understood by means of spatial distribution of new-generated ions from the comet nucleus with the homogenous flow of the solar wind plasma. This research also provides the final equations for the image of the comet (Lovejoy) using the Matlab. We have fitted a function to the 1-D intensity distribution through the major axis that passing the centers of the nucleus of comet .this intensity distribution is really related to the number .of photon that reflected from the sun this equation leads us to predict the temperature and density distribution from the observed comet by optical telescope.
