The present paper focuses on the study of some characteristics ofcomets ions by photometry method which represent by CCD camerawhich it provide seeing these images in a graded light. From 0-255when Zero (low a light intensity) and 255 (highlight intensity). Thesedifferences of photonic intensity can be giving us a curve whichappear from any line of this image.From these equations the focus is concentrating on determine thetemperature distribution, velocity distribution, and intensity numberdistribution which is give number of particles per unit volume.The results explained the interaction near the cometary nucleuswhich is mainly affected by the new ions added to the density of thesolar wind, the average molecular weight increase and result in manyunique characteristics of the cometary tail.
